Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

You should read the following discussion and analysis of our financial condition and results of operations in conjunction with the consolidated financial statements and the related notes included elsewhere in this Annual Report on Form 10-K. In addition to historical financial information, this discussion contains forward-looking statements based upon current expectations that involve risks and uncertainties. As a result of many factors, including those factors set forth in the “Risk Factors” section of this Annual Report on Form 10-K, our actual results could differ materially from the results described or implied by the forward-looking statements contained in the following discussion and analysis.

Overview

We are a clinical-stage precision oncology company developing novel targeted therapies for RAS-addicted cancers. We possess sophisticated structure-based drug discovery capabilities built upon deep chemical biology and cancer pharmacology know-how and innovative, proprietary technologies that enable the creation of small molecules tailored to unconventional binding sites. Guided by our understanding of genetic drivers and adaptive resistance mechanisms in cancer, we deploy precision medicine approaches to inform innovative monotherapy and combination regimens.

Our research and development pipeline comprises RAS(ON) inhibitors that bind directly to RAS variants, which we refer to as RAS(ON) Inhibitors, and RAS companion inhibitors that target key nodes in the RAS pathway or associated pathways. Our RAS(ON) Inhibitors are designed to be used as monotherapy, in combination with other RAS(ON) Inhibitors and/or in combination with RAS companion inhibitors or other therapeutic agents.

RAS(ON) Inhibitors

Our RAS(ON) Inhibitors are based on our proprietary tri-complex technology platform, which enables a highly differentiated approach to inhibiting the active, GTP-bound form of RAS, which we refer to as RAS(ON). We are developing a portfolio of compounds that we believe were the first RAS(ON) Inhibitors to use this mechanism of action. We believe that direct inhibitors of RAS(ON) suppress cell growth and survival and are less susceptible to adaptive resistance mechanisms recognized for RAS(OFF) inhibitors.

We are evaluating our RAS(ON) Inhibitors alone and in combination with other drugs and investigational drug candidates, particularly in-pathway agents. We believe tailored RAS(ON) Inhibitors will be useful to serve the diverse landscape of RAS-addicted cancers optimally. We believe that in some cases, patients may experience maximal clinical benefit from the broad activity of our RAS(ON) multi-selective inhibitor, daraxonrasib (RMC-6236), if approved. In others, we believe treatment with a RAS(ON) mutant-selective inhibitor may be optimal. We further believe that in some cases, it could be beneficial to combine daraxonrasib with a RAS(ON) mutant-selective inhibitor, with daraxonrasib functioning as the backbone of these RAS(ON) Inhibitor doublets. In addition, we believe that in some cases, combination of our RAS(ON) Inhibitors with standard of care therapies, including immunotherapies, may be optimal.

We are advancing a deep pipeline of RAS(ON) Inhibitors, including daraxonrasib (RMC-6236), our RAS(ON) multi-selective inhibitor; elironrasib (RMC-6291), our G12C-selective inhibitor; and zoldonrasib (RMC-9805), our G12D-selective inhibitor. Together, we consider these three clinical-stage candidates as the first wave of RAS(ON) inhibitors that we are advancing through clinical development. We also currently plan to advance RMC-5127 (G12V) into clinical development. In addition, we have other preclinical-stage RAS(ON) inhibitor clinical development opportunities, including the RAS(ON) mutant-selective inhibitors RMC-0708 (Q61H) and RMC-8839 (G13C).

Daraxonrasib (RMC-6236)

Daraxonrasib (RMC-6236), our RAS(ON) multi-selective inhibitor, is designed as an oral, RAS-selective tri-complex inhibitor of multiple RAS(ON) variants containing cancer driver mutations at all three of the major RAS mutation hotspot positions (G12, G13 and Q61). Daraxonrasib inhibits all three major RAS isoforms, suppressing the mutant cancer driver and cooperating wild-type RAS proteins.

A global, randomized Phase 3 registrational trial of daraxonrasib in the second-line (2L) treatment of patients with metastatic pancreatic ductal adenocarcinoma (PDAC), which we call the RASolute 302 study, is ongoing. In the RASolute 302 study, we are randomizing patients in a 1:1 ratio to receive either daraxonrasib at a dose of 300 mg daily or the investigator’s choice of chemotherapy. The RASolute 302 study has a nested trial design allowing for a hierarchical sequence of statistical analysis, with patients with tumors harboring RAS G12X mutations serving as the core population which will be tested first and all enrolled patients serving as the secondary population. We believe this nested design and hierarchical testing increases the probability of trial success based on the core population while creating an opportunity to gain approval for a broader population. Patients in the RASolute 302 study will be evaluated for the dual primary endpoints of progression-free survival (PFS) and overall survival (OS) in the core

89

population, with secondary endpoints including PFS and OS in the secondary population and objective response rate (ORR) and quality of life measures. We currently expect to substantially complete enrollment of the RASolute 302 study in 2025, to enable an expected clinical readout in 2026.

Having finalized the study protocol, we are now activating sites for a global, randomized Phase 3 registrational trial comparing daraxonrasib versus docetaxel in patients with locally advanced or metastatic RAS-mutated non-small cell lung cancer (NSCLC) who have been treated with immunotherapy and platinum-containing chemotherapy, which we call the RASolve 301 study. In the RASolve 301 study, we are randomizing patients in a 1:1 ratio to receive either daraxonrasib or docetaxel. The RASolve 301 study has a nested trial design allowing for a hierarchical sequence of statistical analysis, with patients with tumors harboring RAS G12X (other than G12C) mutations serving as the core population which will be tested first, and all enrolled patients serving as the secondary population. We believe this nested design and hierarchical testing increases the probability of trial success based on the core population while creating an opportunity to gain approval for a broader population. Patients in the RASolve 301 study will be evaluated for the dual primary endpoints of PFS and OS in the core population, with secondary endpoints including PFS and OS in the secondary population and ORR and quality of life measures.

We currently expect to initiate a global, randomized Phase 3 daraxonrasib monotherapy study in patients with first-line (1L) metastatic PDAC in the second half of 2025. We also currently expect to initiate a global, randomized Phase 3 monotherapy study of daraxonrasib as adjuvant treatment for patients with resectable PDAC in the second half of 2025.

On December 2, 2024 we reported updated clinical safety, tolerability, and activity data for daraxonrasib from our first-in-human monotherapy study of daraxonrasib, which we refer to as the RMC-6236-001 study, in patients with previously treated RAS-mutant PDAC as of a data cutoff date of July 23, 2024. We believe these data showed that daraxonrasib was generally well tolerated and demonstrated encouraging antitumor activity that supported our initiation of the RASolute 302 study.

Also on December 2, 2024, we reported clinical safety and tolerability data as of a September 30, 2024 data cutoff date for daraxonrasib from the RMC-6236-001 study in patients with NSCLC with tumors harboring RAS mutations. We also reported clinical activity data as of a September 30, 2024 data cutoff date for daraxonrasib from the RMC-6236-001 study in patients with NSCLC with tumors harboring RAS G12X mutations who had received one or two prior lines of therapy which must have included prior immunotherapy and platinum chemotherapy administered either concurrently or sequentially, but not docetaxel, a study population matching the planned RASolve 301 enrollees. We believe these data showed that daraxonrasib was generally well tolerated and demonstrated encouraging antitumor activity that supported our initiation of the RASolve 301 study.

Based on our observations from the RMC-6236-001 study and our preclinical observations, we believe there is a potential opportunity to evaluate daraxonrasib combinations in earlier lines of therapy in multiple tumor types, and we are currently evaluating several exploratory combination regimens that include daraxonrasib in order to assess the potential for development in these settings. These combinations include daraxonrasib with pembrolizumab, daraxonrasib with elironrasib, daraxonrasib with zoldonrasib and daraxonrasib with standard of care chemotherapy agents.

On December 2, 2024, we disclosed initial clinical safety and tolerability data as of a data cutoff date of October 28, 2024 from our clinical study of the combination of daraxonrasib with pembrolizumab, which we believe showed the combination was generally well tolerated with limited hepatotoxicity.

Also on December 2, 2024, we disclosed initial clinical safety, tolerability and activity data as of a data cutoff date of October 28, 2024 from our clinical study of the combination of daraxonrasib with elironrasib, which we believe showed the combination was generally well tolerated and provide initial proof-of-mechanism for a RAS(ON) inhibitor doublet in patients with colorectal cancer (CRC) who were previously treated with KRAS(OFF) G12C inhibitors. We believe these preliminary data observations support continued development of RAS(ON) inhibitor doublets in a broad range of tumor types and earlier lines of therapy, including 1L patients with NSCLC carrying RAS G12C tumors.

In April 2024, at the American Association for Cancer Research (AACR) Annual Meeting 2024, we reported individual case studies from the RMC-6236-001 study that showed examples of objective responses to daraxonrasib in patients with tumor types beyond PDAC or NSCLC, specifically patients with melanoma and with CRC.

Elironrasib (RMC-6291)

Elironrasib (RMC-6291) is designed as a RAS(ON) oral tri-complex G12C-selective inhibitor. It is designed to exhibit subnanomolar potency for suppressing RAS pathway signaling and growth of RAS G12C-bearing cancer cells and is engineered to be highly selective for RAS G12C over wild-type RAS and other cellular targets. Elironrasib is designed to be differentiated from

90

first-generation KRAS(OFF) G12C inhibitors, which sequester the KRAS(OFF) G12C form, by its mechanism of directly inhibiting the RAS(ON) G12C form.

On October 13, 2023, we reported interim preliminary safety and anti-tumor data from our ongoing first-in-human study of elironrasib, which we refer to as the RMC-6291-001 study, as of an October 5, 2023 data cut-off date, which we believe provide preliminary evidence of clinically meaningful differentiation of elironrasib from KRAS(OFF) G12C inhibitors.

We are evaluating several exploratory combination regimens that include elironrasib in order to assess the potential for development in earlier lines of therapy. These combinations include elironrasib with pembrolizumab and, as discussed in the “Daraxonrasib (RMC-6236)” section above, elironrasib with daraxonrasib. We are also planning a combination study of elironrasib with both daraxonrasib and pembrolizumab.

On December 2, 2024, we disclosed initial clinical safety, tolerability and activity data for the combination of daraxonrasib with elironrasib, as discussed in the “Daraxonrasib (RMC-6236)” section above.

Also on December 2, 2024, we disclosed clinical safety and tolerability data as of a data cutoff date of October 28, 2024 for the combination of elironrasib with pembrolizumab, which we believe showed the combination was generally well tolerated with limited hepatotoxicity.

Zoldonrasib (RMC-9805)

Zoldonrasib (RMC-9805) is designed as a RAS(ON) oral tri-complex G12D-selective inhibitor. It is designed to exhibit low nanomolar potency for suppressing RAS pathway signaling and growth of RAS G12D-bearing cancer cells and is engineered to covalently inactivate RAS G12D irreversibly.

On October 25, 2024, we reported preliminary clinical safety, tolerability and activity data as of a data cutoff date of September 2, 2024 from our first-in-human monotherapy study of zoldonrasib, which we refer to as the RMC-9805-001 study in patients with previously treated solid tumors harboring KRAS G12D mutations.

We believe that these data support our ongoing development of zoldonrasib as a single agent and in combination with other therapies, including with daraxonrasib. An exploratory combination study of zoldonrasib with daraxonrasib is ongoing. We currently expect to disclose additional zoldonrasib clinical safety and antitumor activity data in the second quarter of 2025.

We currently expect to initiate one or more pivotal combination studies in 2026 that incorporate either zoldonrasib or elironrasib and currently expect to share clinical data supporting these plans in the second or third quarter of 2025.

RMC-5127

RMC-5127 is designed as a RAS(ON) oral G12V-selective inhibitor. It is designed to exhibit picomolar potency for suppressing RAS pathway signaling and growth of RAS G12V-bearing cancer cells and is engineered for selective inhibition of RAS G12V over other RAS isoforms via non-covalent binding interactions. We currently expect to advance RMC-5127 to a clinic-ready stage in 2025 and to initiate a first-in-human dose escalation clinical trial of RMC-5127 in 2026.

RMC-0708

RMC-0708 is designed as a RAS(ON) oral Q61H-selective inhibitor. It is designed to exhibit picomolar potency for suppressing RAS pathway signaling and growth of RAS Q61H-bearing cancer cells and is engineered for selective inhibition of RAS Q61H over other RAS isoforms via non-covalent binding interactions. Clinical development of RMC-0708 is subject to our continuing assessment of our portfolio priorities.

RMC-8839

RMC-8839 is designed as a RAS(ON) oral G13C-selective inhibitor. It is designed to exhibit picomolar potency for suppressing RAS pathway signaling and growth of KRAS G13C-bearing cancer cells and is engineered to covalently inactivate KRAS G13C for irreversible inhibition. Clinical development of RMC-8839 is subject to our continuing assessment of our portfolio priorities.

Other Development Opportunities

We have developed RAS companion inhibitors that are designed to suppress cooperating targets and pathways that sustain RAS-addicted cancers. These compounds include RMC-4630, which is designed as a potent and selective inhibitor of SHP2; RMC-5552,

91

which is designed as a selective inhibitor of mTORC1 signaling in tumors; and RMC-5845, which is designed to target SOS1 a protein that plays a key role in converting RAS(OFF) to RAS(ON) in cells. Additional clinical development of our RAS companion inhibitors is subject to our continuing assessment of our portfolio priorities.

We are also developing preclinical next-generation programs that are designed to sustain our innovation platform beyond our current development-stage assets.

Acquisition of EQRx, Inc.

On November 9, 2023 (the Closing Date), we completed the acquisition of EQRx, Inc. (the EQRx Acquisition), pursuant to the Agreement and Plan of Merger, dated as of July 31, 2023 (the Merger Agreement). Pursuant to the Merger Agreement, EQRx, LLC survived as our wholly owned subsidiary.

On the Closing Date, each share of EQRx, Inc. common stock issued and outstanding immediately prior to the completion of the EQRx Acquisition was converted into the right to receive 0.1112 shares of our common stock. Outstanding stock options, restricted stock units and restricted stock awards of EQRx, Inc. were also converted into our common stock subject to the terms of the Merger Agreement. We issued 54.8 million shares of our common stock and paid $4.0 million in taxes to satisfy statutory income tax withholding obligations in conjunction with the EQRx Acquisition.

As a result of the EQRx Acquisition, we acquired $1.1 billion in net cash, cash equivalents and marketable securities after deducting estimated EQRx wind-down and transaction costs.

For additional information regarding the terms of the EQRx Acquisition, see “Note 3. Acquisition” in the “Notes to Consolidated Financial Statements” contained in Part II, Item 8 of this Annual Report on Form 10-K.

Aethon Collaboration

In March 2024, we entered into a collaboration agreement with Aethon Therapeutics, Inc. (Aethon) pursuant to which Aethon is conducting research related to use of novel bispecific antibodies to mount an immune attack directed at the cancer cells targeted by our RAS(ON) Inhibitors (the Aethon Collaboration Agreement). Pursuant to the Aethon Collaboration Agreement, we agreed to reimburse Aethon for preclinical activities, and we have an option to conduct any clinical or commercial development that may arise from the collaboration.

Financial Operations Overview

Collaboration revenue

Collaboration revenue consisted of revenue under the Sanofi Agreement for our SHP2 program. We received a $50.0 million upfront payment from Sanofi in July 2018 and received reimbursement for research and development services. The Sanofi Agreement was terminated in June 2023.

For further information on our revenue recognition policies, see “Note 2. Summary of significant accounting policies” in the “Notes to Consolidated Financial Statements” contained in Part II, Item 8 of this Annual Report on Form 10-K.

Research and development expenses

We substantially rely on third parties to conduct our preclinical studies, clinical trials and manufacturing. We estimate research and development expenses based on estimates of services performed, and we rely on third party contractors and vendors to provide us with timely and accurate estimates of expenses of services performed to assist us in these estimates. Research and development expenses consist primarily of costs incurred for the development of our product candidates and costs associated with identifying compounds through our discovery platform, which include:

•
external costs incurred under agreements with third-party contract organizations, investigative clinical trial sites that conduct research and development activities on our behalf and consultants;

•
costs related to the production of preclinical, clinical and pre-launch materials, including fees paid to contract manufacturers;

•
laboratory and vendor expenses related to the execution of discovery programs, preclinical and clinical trials;

•
employee-related expenses, which include salaries, benefits and stock-based compensation; and

92

•
facilities and other expenses, which include allocated expenses for rent and maintenance of facilities, depreciation and amortization expense, information technology and other supplies.

We expense all research and development costs in the periods in which they are incurred. Costs for certain development activities are recognized based on an evaluation of the progress to completion of specific tasks using information and data provided to us by our vendors, collaborators and third-party service providers. Nonrefundable advance payments for goods or services to be received in future periods for use in research and development activities are deferred and recorded as prepaid assets. The prepaid amounts are then expensed as the related goods are delivered or as services are performed.

We expect our research and development expenses to increase for the foreseeable future as we continue to invest in discovering and developing product candidates and advancing product candidates into later stages of development, which may include conducting larger clinical trials. The process of conducting the necessary research and development and clinical trials to seek regulatory approval for product candidates is costly and time-consuming, and the successful development of our product candidates is highly uncertain. As a result, we are unable to determine the duration and completion costs of our research and development projects or clinical trials or if and to what extent we will generate revenue from the commercialization and sale of any of our product candidates, if approved.

General and administrative expenses

General and administrative expenses consist primarily of personnel-related costs, consultants and professional services expenses, including legal, audit, accounting and human resources services, insurance, commercial preparation activities, allocated facilities and information technology costs, and other general operating expenses not otherwise classified as research and development expenses. Personnel-related costs consist of salaries, benefits and stock-based compensation. Facilities costs consist of rent, utilities and maintenance of facilities. We expect our general and administrative expenses to increase for the foreseeable future due to anticipated increases in operating and commercial preparation activities, which may result in increases in personnel-related costs associated with increased headcount, other administrative and professional services, and related overhead needed to support these efforts.

Interest income

Interest income primarily consists of interest earned on and accretion of our cash equivalents and marketable securities.

Results of operations

Comparison of the years ended December 31, 2024 and 2023

93

Collaboration revenue

Collaboration revenue in 2023 consisted of revenue under the Sanofi Agreement, which was terminated in June 2023. Collaboration revenue decreased by $11.6 million, or 100%, during the year ended December 31, 2024 compared to 2023. The decrease in collaboration revenue in 2023 was a result of the termination of the Sanofi Agreement.

Research and development expenses

Our research and development efforts during the year ended December 31, 2024 were focused on our clinical development programs and our preclinical programs. The following table sets forth the components of our research and development expenses for the periods indicated:

Research and development expenses increased by $169.1 million, or 40%, during the year ended December 31, 2024 compared to 2023. The increase in research and development expenses during the year ended December 31, 2024 was primarily due to a $61.0 million increase in daraxonrasib expenses, primarily attributable to higher clinical trial expenses; a $31.8 million increase in salaries and other employee-related expenses due to increased headcount to support our research and development programs; a $23.5 million increase in zoldonrasib expenses, primarily attributable to higher clinical trial expenses; a $22.4 million increase in elironrasib expenses, primarily attributable to higher clinical trial expenses; a $16.8 million increase in stock-based compensation; a $14.9 million increase in other research and development expenses as a result of higher rent, utilities and information technology expenses associated with increased headcount; and a $7.9 million increase in preclinical research portfolio expenses; partially offset by a $9.3 million decrease in other RAS companion inhibitor program expenses.

General and administrative expenses

General and administrative expenses increased by $21.7 million, or 29%, during the year ended December 31, 2024 compared to 2023. The increase in general and administrative expenses during the year ended December 31, 2024 was primarily due to a $6.7 million increase in pre-commercial development expenses; a $4.5 million increase in salaries and other employee-related expenses due to increased headcount; a $4.5 million increase in facilities and other allocated expenses as a result of higher rent, utilities and information technology expenses associated with increased headcount; a $3.3 million increase in legal and accounting fees; and a $1.2 million increase in insurance and other fees.

Interest income

Interest income increased by $39.4 million for the year ended December 31, 2024, compared to 2023 due to a larger cash, cash equivalents and marketable securities balance and higher interest rates.

94

Comparison of the years ended December 31, 2023 and 2022

Collaboration revenue

Collaboration revenue consisted of revenue under the Sanofi Agreement, which was terminated in June 2023. Collaboration revenue decreased by $23.8 million, or 67%, during the year ended December 31, 2023 compared to 2022. The decrease in collaboration revenue in 2023 was a result of lower reimbursed expenses from Sanofi.

Research and development expenses

Research and development expenses increased by $170.1 million, or 67%, during the year ended December 31, 2023 compared to 2022. The increase in research and development expenses during the year ended December 31, 2023 was primarily due to a $72.6 million increase in daraxonrasib expenses, primarily attributable to clinical trial and clinical supply manufacturing expenses as daraxonrasib commenced clinical trials at the end of the second quarter of 2022; a $24.1 million increase in salaries and other employee-related expenses due to increased headcount to support our research and development programs; a $17.0 million increase in our preclinical research portfolio expenses; a $16.0 million increase in stock-based compensation including $3.7 million in connection with the EQRx Acquisition; a $15.8 million increase in zoldonrasib expenses, which commenced clinical trials in the third quarter of 2023; a $12.9 million increase in facilities and other allocated expenses as a result of higher rent, utilities and information technology expenses associated with increased headcount; a $12.6 million increase in elironrasib expenses, which commenced clinical trials in the third quarter of 2022; and a $8.2 million increase in employee-related expenses in connection with the EQRx Acquisition; partially offset by a $9.0 million decrease in SHP2 costs.

General and administrative expenses

General and administrative expenses increased by $35.0 million, or 86%, during the year ended December 31, 2023 compared to 2022. The increase in general and administrative expenses during the year ended December 31, 2023 was primarily due to a $14.6 million increase in stock-based compensation expense including $7.5 million in connection with the EQRx Acquisition; a $7.1 million increase in salaries and other employee-related expenses due to increased headcount; a $6.1 million increase in employee-related expenses in connection with the EQRx Acquisition; a $3.2 million increase in facilities and other allocated expenses as a result of higher rent, utilities and information technology expenses associated with increased headcount; a $2.3 million increase in legal and accounting fees; and a $1.6 million increase in pre-commercial development expenses.

Interest income

Interest income increased by $38.3 million for the year ended December 31, 2023, compared to 2022 due to a larger cash, cash equivalents and marketable securities balance and higher interest rates.

95

Liquidity and Capital Resources

In November 2021, we entered into a sales agreement with Cowen and Company, LLC, an affiliate of TD Securities (USA) LLC (TD Cowen), as amended in March 2024, to sell shares of our common stock, from time to time, with aggregate gross proceeds of up to $250 million, through an at-the-market equity offering program (the 2021 ATM). From November 2021 to August 2024, we sold an aggregate of 6,502,078 shares of our common stock under the 2021 ATM, resulting in gross proceeds to us of $186.0 million. During the year ended December 31, 2024, we sold an aggregate of 1,294,050 shares of common stock under the 2021 ATM, resulting in gross proceeds of $60.8 million. In August 2024, we terminated the 2021 ATM and entered into a new sales agreement with TD Cowen to sell shares of our common stock, from time to time, with aggregate gross proceeds of up to $500 million, through an at-the-market equity offering program (the 2024 ATM). Through December 31, 2024, we have sold an aggregate of 1,147,893 shares of common stock under the 2024 ATM, resulting in gross proceeds of $60.4 million.

In July 2022, we issued 13,225,000 shares of our common stock in an underwritten public offering at a price to the public of $20.00 per share, for net proceeds of $248.1 million, after deducting underwriting discounts and commissions of $15.9 million and offering expenses of $0.5 million.

In March 2023, we issued 15,681,818 shares of our common stock in an underwritten public offering at a price to the public of $22.00 per share, for net proceeds of $323.7 million, after deducting underwriting discounts and commissions of $20.7 million and expenses of $0.6 million.

In November 2023, we completed the EQRx Acquisition and issued 54,786,528 shares of common stock in the transaction in which we received approximately $1.1 billion in net cash, cash equivalents and marketable securities after deducting EQRx wind-down and transition costs.

In December 2024, we issued and sold in an underwritten public offering (i) 16,576,088 shares of our common stock at a price to the public of $46.00 per share and (ii) pre‑funded warrants to certain investors to purchase an aggregate of 2,173,917 shares of our common stock at a price of $45.9999 per pre-funded warrant. Each pre-funded warrant will be exercisable from the date of issuance until fully exercised, subject to an ownership limitation. Total net proceeds from the offering were $823.0 million, after deducting underwriting discounts and commissions of $38.8 million and expenses of $0.6 million.

Our operations have been financed primarily by our public offerings of common stock, the EQRx Acquisition and $188.7 million received under the Sanofi Agreement from June 2018 through June 2023 for upfront payments and for research and development cost reimbursement.

As of December 31, 2024, we had $2.3 billion in cash, cash equivalents and marketable securities.

As of December 31, 2024, we had an accumulated deficit of $1.7 billion. Our primary use of cash is to fund operating expenses, which consist primarily of research and development expenditures related to our product candidates and our pre-clinical research portfolio, and to a lesser extent, general and administrative expenditures. We expect our expenses to continue to increase in connection with our ongoing activities, particularly as we continue to advance our product candidates into later stages of development, which includes conducting larger clinical trials, and increase our efforts of preparing to become a commercial-stage company.

We believe that our existing cash, cash equivalents and marketable securities will enable us to fund our planned operations for at least 12 months following the date of this Annual Report on Form 10-K.

The timing and amount of our future funding requirements depends on many factors, including:

•
the scope, progress, results and costs of researching and developing our product candidates and programs, and of conducting preclinical studies and clinical trials;

•
the cost of manufacturing our current and future product candidates for clinical trials in preparation for marketing approval and in preparation for commercialization;

•
the timing of, and the costs involved in, obtaining marketing approvals for our product candidates if clinical trials are successful;

•
the cost of commercialization activities for any of our product candidates, whether alone or in collaboration, including marketing, sales and distribution costs if any product candidate is approved for sale;

•
our ability to establish and maintain strategic licenses or other arrangements and the financial terms of such agreements;

•
the costs involved in preparing, filing, prosecuting, maintaining, expanding, defending and enforcing patent claims, including litigation costs and the outcome of such litigation;

96

•
the timing, receipt and amount of sales of, profit share or royalties on, our future products, if any;

•
the emergence of competing cancer therapies or other adverse market developments; and

•
any plans to acquire or in-license other programs or technologies.

We will require substantial additional financing for our development efforts for our current and future programs and to prepare for their potential commercialization. We do not have any committed external source of funds or other support for these activities, and we expect to finance our cash needs through a combination of public or private equity offerings, debt financings, credit or loan facilities, acquisitions, collaborations, strategic alliances, licensing arrangements and other marketing or distribution arrangements. In addition, we may seek additional capital due to favorable market conditions or strategic considerations even if we believe we have sufficient funds for our current or future operating plans. If we need to raise additional capital to fund our operations, funding may not be available to us on acceptable terms, or at all. If we are unable to obtain adequate financing when needed, we may have to (i) delay, limit, reduce the scope of or terminate one or more of our preclinical studies, clinical trials, or other research and development activities or eliminate one or more of our development programs altogether; or (ii) delay, limit, reduce the scope of or terminate our efforts to establish manufacturing and sales and marketing capabilities or other activities that may be necessary to commercialize any future approved products, or reduce our flexibility in developing or maintaining our sales and marketing strategy.

Cash Flows

The following table summarizes our consolidated cash flows for the periods indicated:

Cash used in operating activities

During the year ended December 31, 2024, cash used in operating activities of $557.4 million was attributable to a net loss of $600.1 million, partially offset by $42.3 million in non-cash charges and by a net change of $0.4 million in our operating assets and liabilities. The non-cash charges primarily consisted of stock-based compensation expense of $79.2 million, depreciation and amortization of $7.6 million, amortization of operating lease right-of-use asset of $4.2 million, offset by net amortization of premium on marketable securities of $44.6 million and change in the fair value of warrant liability and contingent earn-out shares of $4.3 million. The change in operating assets and liabilities was primarily due to a $9.7 million increase in prepaid expenses and other current assets, a $5.9 million increase in other noncurrent assets, a $6.5 million decrease in accounts payable, offset by a $22.0 million increase in accrued expenses and other current liabilities primarily related to clinical trial and clinical supply manufacturing expenses and increased personnel related expenses due to increased headcount and a $1.3 million decrease in accounts receivable.

During the year ended December 31, 2023, cash used in operating activities of $350.6 million was attributable to a net loss of $436.4 million, partially offset by $49.0 million in non-cash charges and by a net change of $36.8 million in our operating assets and liabilities. The non-cash charges primarily consisted of stock-based compensation expense of $61.8 million, depreciation and amortization of $6.1 million, amortization of operating lease right-of-use asset of $3.2 million, offset by net amortization of premium on marketable securities of $22.2 million. The change in operating assets and liabilities was primarily due to a $2.6 million increase in prepaid expenses and other current assets, a $4.5 million decrease in deferred revenue associated with the Sanofi Agreement, a $1.5 million decrease in operating lease liability, a $3.9 million decrease in deferred tax liability, a $1.4 million increase in other noncurrent assets, offset by a $32.5 million increase in accounts payable, $14.7 million increase in accrued expenses and other current liabilities primarily related to clinical trial and clinical supply manufacturing expenses and increased personnel related expenses due to increased headcount and a $3.4 million decrease in accounts receivable.

During the year ended December 31, 2022, cash used in operating activities of $224.4 million was attributable to a net loss of $248.7 million and by a net change of $13.5 million in our operating assets and liabilities, partially offset by $37.8 million in non-cash charges. The non-cash charges primarily consisted of stock-based compensation expense of $31.2 million, depreciation and amortization of $5.0 million, amortization of operating lease right-of-use asset of $4.6 million offset by net amortization of premium on marketable securities of $3.1 million. The change in operating assets and liabilities was primarily due to a $3.8 million increase in prepaid expenses and other current assets primarily resulting from the timing of prepayments made for research and development activities, a $14.5 million decrease in deferred revenue associated with the Sanofi Agreement, a $2.4 million decrease in operating

97

lease liability, offset by a $7.3 million increase in accounts payable, $1.5 million increase in accrued expenses and other current liabilities and a $1.3 million decrease in accounts receivable.

Cash used in investing activities

During the year ended December 31, 2024, cash used in investing activities of $554.4 million was primarily comprised of purchases of marketable securities of $2.1 billion and purchases of property and equipment of $10.3 million, offset by cash provided by maturities of marketable securities of $1.6 billion.

During the year ended December 31, 2023, cash used in investing activities of $342.6 million was primarily comprised of purchases of marketable securities of $1.1 billion and purchases of property and equipment of $7.7 million, offset by cash provided by maturities of marketable securities of $724.0 million.

Cash provided by financing activities

During the year ended December 31, 2024, cash provided by financing activities of $959.4 million was comprised of $823.0 million in net proceeds from the issuance of common stock and pre-funded warrants from the December 2024 underwritten public offering, $118.7 million in net proceeds from the issuance of common stock under the 2024 ATM and the 2021 ATM, $12.3 million in proceeds from the issuance of common stock upon the exercise of stock options and $5.0 million in proceeds from the issuance of common stock under the employee stock purchase plan.

During the year ended December 31, 2023, cash provided by financing activities of $1.2 billion was comprised of $840.8 million of cash, cash equivalents and restricted cash acquired, net of $20.7 million transaction costs in connection with the EQRx Acquisition, $323.7 million in net proceeds from the March 2023 underwritten public offering, $62.1 million in net proceeds from the issuance of common stock under the 2021 ATM, $3.3 million in proceeds from the issuance of common stock under the employee stock purchase plan and $3.3 million in proceeds from the issuance of common stock upon the exercise of stock options, offset by $4.0 million in tax payments in satisfaction of withholding tax requirements pursuant to the EQRx Acquisition.

During the year ended December 31, 2022, cash provided by financing activities of $301.4 million was comprised of $248.1 million in net proceeds from the July 2022 underwritten public offering, $49.9 million in net proceeds from the issuance of common stock under the 2021 ATM, $1.9 million in proceeds from the issuance of common stock under the employee stock purchase plan and $1.5 million in proceeds from the issuance of common stock upon the exercise of stock options.

Contractual Obligations and Commitments

We have contractual obligations related to our office and laboratory space lease in Redwood City, California, described in “Note 7. Commitments and contingencies” in the “Notes to Consolidated Financial Statements” contained in Part II, Item 8 of this Annual Report on Form 10-K.

We enter into agreements in the ordinary course of business with contract research organizations for clinical trials, contract manufacturing organizations to provide clinical trial materials and with vendors for preclinical studies and other services and products for operating purposes which are generally cancelable at any time by us upon 30 to 90 days prior written notice.

Indemnification Agreements

We enter into standard indemnification arrangements in the ordinary course of business. Pursuant to these arrangements, we indemnify, hold harmless and agree to reimburse the indemnified parties for losses suffered or incurred by the indemnified party, in connection with any trade secret, copyright, patent or other intellectual property infringement claim by any third party with respect to its technology. The term of these indemnification agreements is generally perpetual any time after the execution of the agreement. The maximum potential amount of future payments we could be required to make under these arrangements is not determinable. We have never incurred costs to defend lawsuits or settle claims related to these indemnification agreements. As a result, we believe the fair value of these agreements is minimal.

Critical Accounting Policies, Significant Judgments and Use of Estimates

Our management’s discussion and analysis of our financial condition and results of operations is based on our consolidated financial statements, which have been prepared in accordance with United States generally accepted accounting principles (U.S.

98

GAAP). The preparation of these consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements, as well as the reported expenses incurred during the reporting periods. Our estimates are based on our historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. We believe that the accounting policies discussed below are critical to understanding our historical and future performance, as these policies relate to the more significant areas involving management’s judgments and estimates.

Revenue recognition

We recognize revenue in accordance with Accounting Standards Codification Topic 606, Revenue from Contracts with Customers (ASC 606). Under ASC 606, an entity recognizes revenue when its customer obtains control of promised goods or services, in an amount that reflects the consideration which such entity expects to receive in exchange for those goods or services. In determining the appropriate amount of revenue to be recognized as we fulfill our obligations under arrangements, we perform the following steps: (i) identify the contract(s) with a customer, (ii) identify the performance obligations in the contract, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations in the contract, and (v) recognize revenue when (or as) the entity satisfies the performance obligation. At contract inception, once the contract is determined to be within the scope of ASC 606, we assess the goods or services promised within each contract and determine those that are performance obligations and assess whether each promised good or service is distinct. We then recognize as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied.

We enter into collaboration agreements under which we may obtain upfront license fees, research and development funding, and development, regulatory and commercial milestone payments and royalty payments. Our performance obligations under these arrangements may include licenses of intellectual property, sales and distribution rights, research and development services, delivery of manufactured product and/or participation on joint steering committees.

Licenses of intellectual property: If the license to our intellectual property is determined to be distinct from the other performance obligations identified in the arrangement, we recognize revenue from upfront license fees allocated to the license when the license is transferred to the customer and the customer is able to use and benefit from the license. For licenses that are bundled with other promises, we utilize judgment to assess the nature of the combined performance obligation to determine whether the combined performance obligation is satisfied over time or at a point in time and, if over time, the appropriate method of measuring proportional performance for purposes of recognizing revenue from non-refundable, upfront fees. We evaluate the measure of proportional performance each reporting period and, if necessary, adjust the measure of performance and related revenue recognition.

Research, development and regulatory milestone payments: At the inception of each arrangement that includes research, development, or regulatory milestone payments, we evaluate whether the milestones are considered probable of being reached and estimate the amount to be included in the transaction price. We use the most likely amount method for research, development and regulatory milestone payments. Under the most likely amount method, an entity considers the single most likely amount in a range of possible consideration amounts. If it is probable that a significant revenue reversal would not occur, the associated milestone value is included in the transaction price.

Sales-based milestones and royalties: For arrangements that include sales-based milestone or royalty payments based on the level of sales, and in which the license is deemed to be the predominant item to which the sales-based milestone or royalties relate to, we recognize revenue in the period in which the sales-based milestone is achieved and in the period in which the sales associated with the royalty occur. To date, we have not recognized any sales-based milestone or royalty revenue resulting from our collaboration arrangements.

The transaction price for each collaboration agreement is determined based on the amount of consideration we expect to be entitled for satisfying all performance obligations within the agreement. Significant judgment may be required in determining the amount of variable consideration to be included in the transaction price. We use the most likely amount method to determine variable consideration and will re-evaluate the transaction price in each reporting period and as uncertain events are resolved or other changes in circumstances occur.

99

Revenue is recognized based on actual costs incurred as a percentage of total estimated costs to be incurred over the performance obligation as we fulfill our performance obligations. A cost-based input method of revenue recognition requires management to make estimates of costs to complete our performance obligations. In making such estimates, significant judgment is required to evaluate assumptions related to cost estimates. The cumulative effect of revisions to estimated costs to fulfill our performance obligations will be recorded in the period in which changes are identified and amounts can be reasonably estimated.

Accrued research and development expenses

We accrue for estimated costs of research and development activities performed by third-party service providers, which include pre-clinical studies, clinical trials and contract manufacturing activities. We record the estimated costs of research and development activities based upon the estimated services provided but not yet invoiced and include these costs in accrued expenses and other payables in our consolidated balance sheets and within research and development expense in our consolidated statements of operations. We accrue for these costs based on various factors such as estimates of the work completed and in accordance with agreements established with our third-party service providers. Further, we accrue expenses related to clinical trials based on the level of patient enrollment and activity according to the related agreement. We monitor patient enrollment levels and related activity to the extent reasonably possible and make judgments and estimates in determining the accrued balance in each reporting period. If we underestimate or overestimate the level of services performed or the costs of these services, our actual expenses could differ from our estimates. To date, we have not experienced significant changes in our estimates of preclinical studies and clinical trial accruals.

Stock-based compensation

We maintain an equity incentive plan as a long-term incentive for employees, consultants and members of our board of directors. The plan allows for the issuance of non-statutory options (NSOs), incentive stock options (ISOs), restricted stock unit awards (RSUs) to employees and NSOs and RSUs to nonemployees.

Stock-based compensation is measured using estimated grant date fair value and recognized as compensation expense over the service period in which the awards are expected to vest. The grant date fair value of an RSU award is based on our stock price on the date of grant. For options, we estimate the grant date fair value, and the resulting stock-based compensation, using the Black-Scholes option-pricing model, and we use the straight-line method for expense attribution. The Black-Scholes model requires us to make assumptions and judgments about the variables used in the calculations, including the expected term (weighted-average period of time that the options granted are expected to be outstanding), the expected volatility of our common stock, the related risk-free interest rate and the expected dividend. We have elected to recognize forfeitures of stock-based awards as they occur.

The Black-Scholes option-pricing model requires the use of highly subjective assumptions to determine the fair value of stock-based awards. These assumptions include:

•
Expected Term—The expected term is calculated using the simplified method, which is available where there is insufficient historical data about exercise patterns and post-vesting employment termination behavior. The simplified method is based on the vesting period and the contractual term for each grant, or for each vesting-tranche for awards with graded vesting. The mid-point between the vesting date and the maximum contractual expiration date is used as the expected term under this method.

•
Expected Volatility—Given that we do not have sufficient trading history for our common stock, the expected volatility was estimated based on the average volatility of the Company and comparable publicly traded biotechnology companies over a period equal to the expected term of the stock option grants. The comparable companies were chosen based on their similar size, stage in the life cycle or area of specialty.

•
Risk-Free Interest Rate—The risk-free interest rate is based on the U.S. Treasury zero coupon issues in effect at the time of grant for periods corresponding with the expected term of the option.

•
Expected Dividend—We have never paid dividends on our common stock and have no plans to pay dividends on our common stock. Therefore, we used an expected dividend yield of zero.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

You should read the following discussion and analysis of our financial condition and results of operations in conjunction with the consolidated financial statements and the related notes included elsewhere in this Annual Report on Form 10-K. In addition to historical financial information, this discussion contains forward-looking statements based upon current expectations that involve risks and uncertainties. As a result of many factors, including those factors set forth in the “Risk Factors” section of this Annual Report on Form 10-K, our actual results could differ materially from the results described or implied by the forward-looking statements contained in the following discussion and analysis.

Overview

We are a clinical-stage precision oncology company developing novel targeted therapies for RAS-addicted cancers. We possess sophisticated structure-based drug discovery capabilities built upon deep chemical biology and cancer pharmacology know-how and innovative, proprietary technologies that enable the creation of small molecules tailored to unconventional binding sites. Guided by our understanding of genetic drivers and adaptive resistance mechanisms in cancer, we deploy precision medicine approaches to inform innovative monotherapy and combination regimens.

Our research and development pipeline comprises RAS(ON) inhibitors that bind directly to RAS variants, which we refer to as RAS(ON) Inhibitors, and RAS companion inhibitors that target key nodes in the RAS pathway or associated pathways, which we refer to as RAS Companion Inhibitors. Our RAS(ON) Inhibitors are designed to be used as monotherapy, in combination with other RAS(ON) Inhibitors and/or in combination with RAS Companion Inhibitors or other therapeutic agents. Our RAS Companion Inhibitors are designed primarily for combination treatment strategies centered on our RAS(ON) Inhibitors.

RAS(ON) Inhibitors

Our RAS(ON) Inhibitors are based on our proprietary tri-complex technology platform, which enables a highly differentiated approach to inhibiting the active, GTP-bound form of RAS, which we refer to as RAS(ON). We are developing a portfolio of compounds that we believe are the first and only RAS(ON) Inhibitors to use this mechanism of action. We believe that direct inhibitors of RAS(ON) suppress cell growth and survival and are less susceptible to adaptive resistance mechanisms recognized for RAS(OFF) Inhibitors. We are evaluating our RAS(ON) Inhibitors alone and in combination with other drugs and investigational drug candidates, including with other RAS(ON) Inhibitors in RAS(ON) Inhibitor doublet regimens.

We are advancing a deep pipeline of RAS(ON) Inhibitors, including both our innovative RAS(ON) multi-selective inhibitor (RMC-6236) and a series of mutant-selective inhibitors (led by RMC-6291 and RMC-9805). Together, we consider these three development-stage candidates as the first wave of RAS(ON) inhibitors that we are advancing through clinical development.

RMC-6236

RMC-6236, our RAS(ON) multi-selective inhibitor, is designed as an oral, RAS-selective tri-complex inhibitor of multiple RAS(ON) variants containing cancer driver mutations at all three of the major mutation hotspot positions, G12, G13, and Q61. RMC-6236 inhibits all three major RAS isoforms, suppressing the mutant cancer driver and cooperating wild-type RAS proteins.

A monotherapy dose-escalation Phase 1/1b study of RMC-6236, which we refer to as the RMC-6236-001 study, is ongoing. On October 13, 2023, we reported updated interim safety, pharmacokinetic (PK) and circulating tumor DNA (ctDNA) data from the RMC-6236-001 study as of a September 11, 2023 data cut-off date. These data demonstrated that RMC-6236 was generally well tolerated across dose levels in patients with solid tumors. These data also demonstrated dose-dependent increases in exposure at a steady state with minimal accumulation after repeated daily oral dosing, which we believe is compatible with once-daily dosing. Reductions in ctDNA variant allele frequency were observed for multiple KRAS-mutated alleles in multiple tumor types, indicative of anti-tumor activity by RMC-6236.

On October 22, 2023, we reported updated interim safety and anti-tumor activity data for dose levels of 80 mg daily and above from the RMC-6236-001 study as of an October 12, 2023 data cut-off date. These data demonstrated that RMC-6236 was generally well tolerated across the dose levels analyzed as of the cut-off date. These data also demonstrated preliminary evidence of clinical activity in non-small cell lung cancer (NSCLC) patients and pancreatic ductal adenocarcinoma (PDAC) patients.

On January 9, 2024, we reported that, with additional follow-up after the October 2023 data reports described above, the profile of RMC-6236 remained relatively consistent with the description in the October 2023 reports, the objective response rate (ORR) for both NSCLC and PDAC patients had improved, and the disease control rate (DCR) remained consistent.

We currently expect to disclose updated clinical safety, tolerability and activity data from the RMC-6236-001 study for patients with NSCLC and for patients with PDAC in the second half of 2024. We also currently expect to disclose initial data from

86

Phase 1 expansion cohorts in the RMC-6236-001 study in tumor types beyond NSCLC and PDAC and genotypes beyond KRAS G12X in the second or third quarter of 2024.

We are also evaluating RMC-6236 in a series of combination regimens. We are conducting an open-label Phase 1b/2 platform study evaluating our RAS(ON) Inhibitors in combination with standard(s) of care in advanced NSCLC patients, which we refer to as the RMC-LUNG-101 study. There are currently two ongoing subprotocols under RMC-LUNG-101, one evaluating our RAS(ON) G12C inhibitor, RMC-6291, which we refer to as the RMC-LUNG-101A, and one evaluating RMC-6236, which we refer to as the RMC-LUNG-101B study. RMC-LUNG-101B is a Phase 1b/2 dose exploration and dose expansion study evaluating RMC-6236 in combination with pembrolizumab, with or without chemotherapy, in patients with RAS-mutated NSCLC. We currently expect to disclose initial clinical PK, safety, tolerability and activity data from the RMC-LUNG-101B study in the second half of 2024.

We are also conducting an open-label Phase 1b clinical trial of RMC-6291 in combination with RMC-6236, which we refer to as the RMC-6291-101 study. This study is ongoing, and we currently expect to disclose initial clinical PK, safety, tolerability and activity data in the second half of 2024.

Planning is also underway for one or more combination clinical trials for RMC-6236 with standard of care therapies in first-line treatment settings.

We are planning a global randomized Phase 3 trial comparing RMC-6236 against docetaxel in patients with RAS-mutated NSCLC who have been treated with immunotherapy and platinum-containing chemotherapy. The study design for this planned trial is subject to change based on regulatory authority feedback. We currently expect to initiate this study in the second half of 2024.

We are also planning a global randomized Phase 3 trial comparing RMC-6236 against a physician’s choice of chemotherapy regimens in patients with previously treated RAS-mutated PDAC. The study design for this planned trial is subject to change based on regulatory authority feedback. We currently expect to initiate this study in the second half of 2024.

RMC-6291

RMC-6291 is designed as a RAS(ON) oral tri-complex G12C-selective inhibitor. It is designed to exhibit subnanomolar potency for suppressing RAS pathway signaling and growth of RAS G12C-bearing cancer cells and is engineered to be highly selective for RAS G12C over wild-type RAS and other cellular targets. RMC-6291 is designed to be differentiated from first-generation KRAS(OFF) G12C inhibitors, which sequester the KRAS(OFF) G12C form, by its mechanism of directly inhibiting the RAS(ON) G12C form.

A monotherapy dose-escalation Phase 1b study of RMC-6291, which we refer to as the RMC 6291-001 study, is ongoing.

On October 13, 2023, we reported interim preliminary safety and anti-tumor data from the RMC-6291-001 study as of an October 5, 2023 data cut-off date. The data demonstrated that RMC-6291 was generally well tolerated across dose levels. These data also demonstrated preliminary evidence of clinical activity in patients with KRAS G12C NSCLC previously treated with, or naïve to, a KRAS(OFF) G12C inhibitor and preliminary evidence of clinical activity in patients with KRAS G12C colorectal cancer (CRC) who were naïve to treatment with a KRAS(OFF) G12C inhibitor. We observed that RMC-6291 was orally bioavailable and demonstrated dose-dependent pharmacokinetics and that reduction in ctDNA of the KRAS G12C allele across doses was correlated with clinical response. We believe these data provide preliminary evidence of clinically meaningful differentiation of RMC-6291 from KRAS(OFF) G12C inhibitors.

On January 9, 2024, we reported that relative to the October 13, 2023 report, profile of RMC-6291 in the RMC-6291-001 study had remained relatively stable. We continue dosing patients at a 200 mg BID dose.

As discussed above in the “RMC-6236” section, we are evaluating RMC-6291 in the RMC-LUNG-101A study, which is a Phase 1b/2 dose exploration and dose expansion study evaluating RMC-6291 in combination with pembrolizumab, with or without chemotherapy, in patients with RAS-mutated NSCLC. We currently expect to disclose initial clinical PK, safety, tolerability and activity data from the RMC-LUNG-101A study in the second half of 2024.

As also discussed above in the “RMC-6236” section, we are conducting an open-label Phase 1/1b clinical trial of RMC-6291 in combination with RMC-6236, which we refer to as the RMC-6291-101 study.

RMC-9805

RMC-9805 is designed as a RAS(ON) oral tri-complex G12D-selective inhibitor. It is designed to exhibit low nanomolar potency for suppressing RAS pathway signaling and growth of RAS G12D-bearing cancer cells and is engineered to covalently inactivate RAS G12D irreversibly.

87

A monotherapy dose-escalation Phase 1/1b trial of RMC-9805, which we refer to as the RMC-9805-001 study, is ongoing.

On January 9, 2024, we reported that, based on our observations of interim data from the RMC-9805-001 study, RMC-9805 demonstrated oral bioavailability in patients, exhibiting PK consistent with expectations from preclinical data. We also reported that the compound had cleared several dose levels and that we observed favorable tolerability results with no dose-limiting toxicities reported, and that a recommended Phase 2 dose and schedule was not yet reached.

We currently expect to disclose initial clinical PK, safety, tolerability and activity data from the RMC-9805-001 study in the second half of 2024.

Additional RAS(ON) Inhibitors

Beyond this first wave of RAS(ON) Inhibitors, we have other RAS(ON) Inhibitor compounds currently in our research and development pipeline, including the development candidates RMC-5127 (G12V), RMC-0708 (Q61H) and RMC-8839 (G13C). We are also pursuing pipeline expansion programs focused on G12R and other targets.

RAS Companion Inhibitors

RMC-4630

Our RAS Companion Inhibitor RMC-4630 is designed as a potent and selective inhibitor of SHP2.

Amgen is currently evaluating RMC-4630 in a Phase 1b study in combination with Amgen’s KRAS(OFF) G12C agent sotorasib (LUMAKRAS®) in Amgen’s CodeBreaK 101c study.

We and Sanofi, our former SHP2 development partner, sponsored several additional studies involving RMC-4630, all of which are being wound down.

The combination of RMC-4630 with an ERK inhibitor in patients with pancreatic cancer is being evaluated as part of an investigator-sponsored study by the Netherlands Cancer Institute.

We have no immediate plans for further development of RMC-4630, but we believe this compound remains an option for potential evaluation in combination regimens.

RMC-5552

Our RAS Companion Inhibitor RMC-5552 is designed as a selective inhibitor of mTORC1 signaling in tumors. We are evaluating RMC-5552 as a monotherapy in a Phase 1 study, which we refer to as the RMC-5552-001 study, and we may evaluate RMC-5552 in combination with RAS(ON) Inhibitors for patients with cancers harboring a RAS mutation and co-occurring mutations in the mTOR signaling pathway.

We reported additional interim data from the ongoing dose-escalation portion of the RMC-5552-001 study in October 2023.

We are supplying RMC-5552 to the Regents of the University of California on behalf of its San Francisco campus (UCSF) for an investigator-initiated Phase 1/1b trial by UCSF of RMC-5552 in patients with recurrent glioblastoma.

RMC-5845

Our RAS Companion Inhibitor RMC-5845 targets SOS1, a protein that plays a key role in converting RAS(OFF) to RAS(ON) in cells. RMC-5845 is intended for select combination therapies for certain genetically defined tumors. This compound is ready for preparation of an IND application based on our preclinical development. We have no plans for further development of RMC-5845 at this time based on our current understanding that it may not offer an advantage over RMC-6236.

Acquisition of EQRx, Inc.

On November 9, 2023 (the Closing Date), we completed the acquisition of EQRx, Inc. (the EQRx Acquisition), pursuant to the Agreement and Plan of Merger, dated as of July 31, 2023 (the Merger Agreement). Pursuant to the Merger Agreement, EQRx, LLC survived as our wholly owned subsidiary.

On the Closing Date, each share of EQRx, Inc. common stock issued and outstanding immediately prior to the completion of the EQRx Acquisition was converted into the right to receive 0.1112 shares of our common stock. Outstanding stock options,

88

restricted stock units and restricted stock awards of EQRx, Inc. were also converted into our common stock subject to the terms of the Merger Agreement. We issued 54.8 million shares of our common stock and paid $4.0 million in taxes to satisfy statutory income tax withholding obligations in conjunction with the EQRx Acquisition.

As a result of the EQRx Acquisition, we acquired approximately $1.1 billion in net cash, cash equivalents and marketable securities after deducting estimated EQRx wind-down and transition costs.

For additional information regarding the terms of the EQRx Acquisition, see “Acquisitions” under Note 3, to our audited consolidated financial statements included in Item 8 of this Annual Report on Form 10-K.

Collaboration agreement with Sanofi

In June 2018, we entered into the Sanofi Agreement with Aventis, Inc. (an affiliate of Sanofi) to research and develop SHP2 inhibitors, including RMC-4630, for any indications. The Sanofi Agreement was assigned to Genzyme Corporation, a Sanofi affiliate, in December 2018. For the purposes of this discussion, we refer to Genzyme Corporation as Sanofi. The Sanofi Agreement was terminated in June 2023.

Pursuant to the Sanofi Agreement, we granted Sanofi a worldwide, exclusive, sublicensable (subject to our consent in certain circumstances) license under certain of our patents and know-how to research, develop, manufacture, use, sell, offer for sale, import and otherwise commercialize SHP2 inhibitors, including RMC-4630, for any and all uses, subject to our exercise of rights and performance of obligations under the Sanofi Agreement.

Under the Sanofi Agreement, we had primary responsibility for early clinical development of RMC-4630 pursuant to an approved development plan. Sanofi was responsible to reimburse us for all internal and external costs and expenses to perform our activities under approved development plans, except for costs and expenses related to the RMC-4630-03 study, for which Sanofi reimbursed us 50% of the costs and expenses.

Pursuant to the Sanofi Agreement, we received an upfront payment of $50.0 million from Sanofi in July 2018. The Sanofi Agreement included obligations for Sanofi to make certain milestone payments and royalty payments, all of which expired on termination of the Sanofi Agreement.

Financial Operations Overview

Collaboration revenue

Collaboration revenue consisted of revenue under the Sanofi Agreement for our SHP2 program. We received a $50.0 million upfront payment from Sanofi in July 2018 and received reimbursement for research and development services. The Sanofi Agreement was terminated in June 2023.

For further information on our revenue recognition policies, see “Note 2. Summary of significant accounting policies” in the “Notes to Consolidated Financial Statements” contained in Part II, Item 8 of this Annual Report on Form 10-K.

Research and development expenses

We substantially rely on third parties to conduct our preclinical studies, clinical trials and manufacturing. We estimate research and development expenses based on estimates of services performed, and rely on third party contractors and vendors to provide us with timely and accurate estimates of expenses of services performed to assist us in these estimates. Research and development expenses consist primarily of costs incurred for the development of our product candidates and costs associated with identifying compounds through our discovery platform, which include:

•
expenses incurred under agreements with third-party contract organizations, investigative clinical trial sites that conduct research and development activities on our behalf and consultants;

•
costs related to production of clinical and preclinical materials, including fees paid to contract manufacturers;

•
laboratory and vendor expenses related to the execution of discovery programs, preclinical and clinical trials;

•
employee-related expenses, which include salaries, benefits and stock-based compensation; and

•
facilities and other expenses, which include allocated expenses for rent and maintenance of facilities, depreciation and amortization expense, information technology and other supplies.

89

We expense all research and development costs in the periods in which they are incurred. Costs for certain development activities are recognized based on an evaluation of the progress to completion of specific tasks using information and data provided to us by our vendors, collaborators and third-party service providers. Nonrefundable advance payments for goods or services to be received in future periods for use in research and development activities are deferred and recorded as prepaid assets. The prepaid amounts are then expensed as the related goods are delivered or as services are performed.

Up to the termination date of the Sanofi Agreement, Sanofi was responsible to reimburse us for all internal and external costs and expenses to perform our activities under approved development plans, except for 50% of the RMC-4630-03 study. These reimbursements from Sanofi are recorded as collaboration revenue.

We expect our research and development expenses to increase for the foreseeable future as we continue to invest in discovering and developing product candidates and advancing product candidates into later stages of development, which may include conducting larger clinical trials. The process of conducting the necessary research and development and clinical trials to seek regulatory approval for product candidates is costly and time-consuming, and the successful development of our product candidates is highly uncertain. As a result, we are unable to determine the duration and completion costs of our research and development projects or clinical trials or if and to what extent we will generate revenue from the commercialization and sale of any of our product candidates.

General and administrative expenses

General and administrative expenses consist primarily of personnel-related costs, consultants and professional services expenses, including legal, audit, accounting and human resources services, insurance, allocated facilities and information technology costs, and other general operating expenses not otherwise classified as research and development expenses. Personnel-related costs consist of salaries, benefits and stock-based compensation. Facilities costs consist of rent, utilities and maintenance of facilities. We expect our general and administrative expenses to increase for the foreseeable future due to anticipated increases in headcount and as a result of operating as a public company, including expenses related to compliance with the rules and regulations of the Securities and Exchange Commission, the Nasdaq Global Select Market, investor relations activities and other administrative and professional services.

Interest income

Interest income primarily consists of interest earned on and accretion of our cash equivalents and marketable securities.

Benefit from income taxes

Benefit from income taxes relates to net changes in the deferred tax liability associated with the Warp Drive acquisition resulting from changes in the effective state tax rate and changes in our valuation allowance.

Results of operations

Comparison of the years ended December 31, 2023 and 2022

Collaboration revenue

Collaboration revenue consisted of revenue under the Sanofi Agreement, which terminated in June 2023. Collaboration revenue decreased by $23.8 million, or 67%, during the year ended December 31, 2023 compared to 2022. The decrease in collaboration revenue in 2023 was a result of lower reimbursed expenses from Sanofi.

Research and development expenses

Research and development expenses increased by $170.1 million, or 67%, during the year ended December 31, 2023 compared to 2022. The increase in research and development expenses during the year ended December 31, 2023 was primarily due to a $72.6 million increase in our RMC-6236 costs, primarily attributable to clinical trial and clinical supply manufacturing expenses as RMC-6236 commenced clinical trials at the end of the second quarter of 2022; a $24.1 million increase in salaries and other employee-related expenses due to increased headcount to support our research and development programs; a $17.0 million increase in our preclinical research portfolio costs; a $16.0 million increase in stock-based compensation including $3.7 million in connection with the EQRx Acquisition; a $15.8 million increase in RMC-9805 costs, which commenced clinical trials in the third quarter of 2023; a $12.9 million increase in facilities and other allocated expenses as a result of higher rent, utilities and information technology expenses associated with increased headcount; a $12.6 million increase in RMC-6291 costs, which commenced clinical trials in the third quarter of 2022; and a $8.2 million increase in employee-related expenses in connection with the EQRx Acquisition; partially offset by a $9.0 million decrease in SHP2 costs.

91

General and administrative expenses

General and administrative expenses increased by $35.0 million, or 86%, during the year ended December 31, 2023 compared to 2022. The increase in general and administrative expenses during the year ended December 31, 2023 was primarily due to a $14.6 million increase in stock-based compensation expense including $7.5 million in connection with the EQRx Acquisition; a $7.1 million increase in salaries and other employee-related expenses due to increased headcount; a $6.1 million increase in employee-related expenses in connection with the EQRx Acquisition; a $3.2 million increase in facilities and other allocated expenses as a result of higher rent, utilities and information technology expenses associated with increased headcount; a $2.3 million increase in legal and accounting fees; and a $1.6 million increase in pre-commercial development expenses.

Interest income

Interest income increased by $38.3 million for the year ended December 31, 2023, compared to 2022 due to a larger cash, cash equivalents and marketable securities balance and higher interest rates.

Benefit from income taxes

Tax benefit from income taxes was $3.5 million for the year ended December 31, 2023 and $0.4 million for the year ended December 31, 2022 and related to a decrease in the effective state tax rate and the resulting impact on the deferred tax liabilities from the Warp Drive acquisition.

Comparison of the years ended December 31, 2022 and 2021

Collaboration revenue

Collaboration revenue consisted of revenue under the Sanofi Agreement, which is expected to terminate in 2023. As a result of the expected termination of the agreement and development plan adjustments during the year, we revised our estimate of the accounting transaction price and increased our percentage of completion under the agreements with Sanofi, which resulted in total cumulative catch-up adjustments that increased collaboration revenue by $3.0 million for the year ended December 31, 2022.

In August 2021, we entered into a Letter Agreement with Sanofi to include RMC-4630-03 under the development plan for RMC-4630 and decided to no longer enroll new patients in RMC-4630-02. As a result of these development plan adjustments, we revised the estimate of the accounting transaction price and decreased our estimated percentage of completion under the agreements with Sanofi, and resulted in a cumulative catch-up adjustment that reduced collaboration revenue by $8.5 million for the year ended December 31, 2021.

Collaboration revenue increased by $6.0 million, or 20%, during the year ended December 31, 2022 compared to the same period in 2021. The increase was due to the cumulative catch-up adjustments resulting from the Sanofi Agreement termination and development plan adjustments, partially offset by lower reimbursable SHP2 program research and development costs under the Sanofi Agreement for the year ended December 31, 2022.

92

Research and development expenses

Research and development expenses increased by $66.1 million, or 35%, during the year ended December 31, 2022 compared to the same period in 2021. The increase in research and development expenses during the year ended December 31, 2022 was primarily due to a $16.1 million increase in third-party costs for our preclinical research portfolio, primarily driven by higher chemistry contract research organization, material sourcing and manufacturing costs; a $16.1 million increase in salaries and other employee-related expenses due to increased headcount to support our research and development programs; a $14.8 million increase in RMC-6236 costs, which commenced clinical trials in the second quarter of 2022; a $10.2 million increase in facilities and other allocated expenses as a result of higher rent, utilities and information technology expenses associated with increased headcount; a $6.3 million increase in stock-based compensation; and a $5.2 million increase in RMC-6291 costs, which commenced clinical trials in the third quarter of 2022.

General and administrative expenses

General and administrative expenses increased by $10.1 million, or 33%, during the year ended December 31, 2022 compared to the same period in 2021. The increase in general and administrative expenses during the year ended December 31, 2022 was primarily due to an increase of $4.2 million in stock-based compensation expense; an increase of $3.9 million in salaries and other employee-related expenses due to increased headcount; a $0.7 million increase in facilities and other allocated expenses as a result of higher rent, utilities and information technology expenses associated with increased headcount; and a $0.8 million increase in legal and accounting fees.

Interest income

Interest income increased by $8.2 million for the year ended December 31, 2022, compared to the same period in 2021 due to a larger cash, cash equivalents and marketable securities balance and higher interest rates.

Benefit from income taxes

Benefit from income taxes was $0.4 million for the year ended December 31, 2022 and zero for the year ended December 31, 2021 and related to net changes in the valuation allowance resulting from the Warp Drive acquisition.

Liquidity and capital resources

In February 2021, we issued 6,666,666 shares of our common stock in an underwritten public offering at a price to the public of $45.00 per share for net proceeds of $281.1 million, after deducting underwriting discounts and commissions of $18.0 million and offering expenses of $0.9 million.

In November 2021, we entered into a sales agreement with Cowen and Company, LLC (Cowen) to sell shares of our common stock, from time to time, with aggregate gross proceeds of up to $250.0 million, through an at-the-market equity offering program (ATM) under which Cowen agreed to act as our sales agent. During the year ended December 31, 2021, we sold an aggregate of 339,302 shares of common stock under the ATM resulting in gross proceeds to us of $10.4 million. After deducting commissions and expenses of $0.3 million, our net proceeds under the ATM were $10.1 million during the year ended December 31, 2021. During the year ended December 31, 2022, we sold an aggregate of 2,385,846 shares of common stock under the ATM resulting in gross proceeds to us of $51.3 million. After deducting commissions and expenses of $1.4 million, our net proceeds under the ATM were $49.9 million during the year ended December 31, 2022. During the year ended December 31, 2023, we sold an aggregate of 2,482,880 shares of common stock under the ATM resulting in gross proceeds to us of $63.5 million. After deducting commissions and expenses of $1.4 million, our net proceeds under the ATM were $62.1 million during the year ended December 31, 2023.

In July 2022, we issued 13,225,000 shares of our common stock in an underwritten public offering at a price to the public of $20.00 per share, for net proceeds of $248.1 million, after deducting underwriting discounts and commissions of $15.9 million and estimated offering expenses of $0.5 million.

In March 2023, we issued 15,681,818 shares of our common stock in an underwritten public offering at a price to the public of $22.00 per share, for net proceeds of $323.7 million, after deducting underwriting discounts and commissions of $20.7 million and expenses of $0.6 million.

In November 2023, we completed the EQRx Acquisition and issued 54,786,528 shares of common stock in a transaction in which we received approximately $1.1 billion in net cash, cash equivalents and marketable securities after deducting estimated EQRx wind-down and transition costs.

93

Our operations have been financed primarily by our public offerings of common stock, the EQRx Acquisition, net proceeds of $230.6 million from the issuance of our preferred stock and $187.7 million received under the Sanofi Agreement for upfront payments and for research and development cost reimbursement.

As of December 31, 2023, we had $1.9 billion in cash, cash equivalents and marketable securities.

As of December 31, 2023, we had an accumulated deficit of $1.1 billion. Our primary use of cash is to fund operating expenses, which consist primarily of research and development expenditures related to our product candidates and our pre-clinical research portfolio, and to a lesser extent, general and administrative expenditures. We expect our expenses to continue to increase in connection with our ongoing activities, particularly as we continue to advance our product candidates and pre-clinical research portfolio.

We believe that our existing cash, cash equivalents and marketable securities will enable us to fund our planned operations for at least 12 months following the date of this report.

The timing and amount of our future funding requirements depends on many factors, including:

•
the scope, progress, results and costs of researching and developing our product candidates and programs, and of conducting preclinical studies and clinical trials;

•
the timing of, and the costs involved in, obtaining marketing approvals for our product candidates if clinical trials are successful;

•
the cost of commercialization activities for any product candidates, whether alone or in collaboration, including marketing, sales and distribution costs if any product candidate is approved for sale;

•
the cost of manufacturing our current and future product candidates for clinical trials in preparation for marketing approval and in preparation for commercialization;

•
our ability to establish and maintain strategic licenses or other arrangements and the financial terms of such agreements;

•
the costs involved in preparing, filing, prosecuting, maintaining, expanding, defending and enforcing patent claims, including litigation costs and the outcome of such litigation;

•
the timing, receipt and amount of sales of, profit share or royalties on, our future products, if any;

•
the emergence of competing cancer therapies or other adverse market developments; and

•
any plans to acquire or in-license other programs or technologies.

We will need to obtain substantial additional funding in the future to continue the preclinical and clinical development of our current and future programs and to prepare for their potential commercialization. If we need to raise additional capital to fund our operations, funding may not be available to us on acceptable terms, or at all. If we are unable to obtain adequate financing when needed, we may have to delay, reduce the scope of or suspend one or more of our clinical trials, research and development programs or commercialization efforts. We may seek to raise any necessary additional capital through a combination of public or private equity offerings, debt financings, acquisitions, and collaborations or licensing arrangements. If we do raise additional capital through public or private equity offerings or acquisitions using our common stock, the ownership interest of our existing stockholders will be diluted, and the terms may include liquidation or other preferences that adversely affect our stockholders’ rights. If we raise additional capital through debt financing, we may be subject to covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends, and if the debt is convertible into our common stock, the ownership interest of our stockholders may be diluted. If we are unable to raise capital, we may need to delay, reduce or terminate planned activities to reduce costs. Doing so will likely harm our ability to execute our business plans.

Cash flows

The following table summarizes our consolidated cash flows for the periods indicated:

94

Cash used in operating activities

During the year ended December 31, 2023, cash used in operating activities of $350.6 million was attributable to a net loss of $436.4 million partially offset by $49.0 million in non-cash charges and by a net change of $36.8 million in our operating assets and liabilities. The non-cash charges primarily consisted of stock-based compensation expense of $61.8 million, depreciation and amortization of $6.1 million, amortization of operating lease right-of-use asset of $3.2 million, offset by net amortization of premium on marketable securities of $22.2 million. The change in operating assets and liabilities was primarily due to a $2.6 million increase in prepaid expenses and other current assets, a $4.5 million decrease in deferred revenue associated with the Sanofi Agreement, a $1.5 million decrease in operating lease liability, a $3.9 million decrease in deferred tax liability, a $1.4 million increase in other noncurrent assets, offset by a $32.5 million increase in accounts payable, $14.7 million increase in accrued expenses and other current liabilities primarily related to clinical trial and clinical supply manufacturing expenses and increased personnel related expenses due to increased headcount and a $3.4 million decrease in accounts receivable.

During the year ended December 31, 2022, cash used in operating activities of $224.4 million was attributable to a net loss of $248.7 million and by a net change of $13.5 million in our operating assets and liabilities partially offset by $37.8 million in non-cash charges. The non-cash charges primarily consisted of stock-based compensation expense of $31.2 million, depreciation and amortization of $5.0 million, amortization of operating lease right-of-use asset of $4.6 million offset by net amortization of premium on marketable securities of $3.1 million. The change in operating assets and liabilities was primarily due to a $3.8 million increase in prepaid expenses and other current assets primarily resulting from the timing of prepayments made for research and development activities, a $14.5 million decrease in deferred revenue associated with the Sanofi Agreement, a $2.4 million decrease in operating lease liability, offset by a $7.3 million increase in accounts payable, $1.5 million increase in accrued expenses and other current liabilities and a $1.3 million decrease in accounts receivable.

During the year ended December 31, 2021, cash used in operating activities of $147.2 million was attributable to a net loss of $187.1 million partially offset by $31.2 million in non-cash charges and by a net change of $8.7 million in our operating assets and liabilities. The non-cash charges primarily consisted of stock-based compensation expense of $20.7 million, depreciation and amortization of $4.2 million, net amortization of premium on marketable securities of $3.0 million and amortization of operating lease right-of-use asset of $3.2 million. The change in operating assets and liabilities was primarily due to an $11.0 million increase in accrued expenses and accounts payable partially offset by a $1.7 million decrease in deferred revenue associated with the Sanofi Agreement and a $1.5 million decrease in operating lease liability.

Cash used in investing activities

During the year ended December 31, 2023, cash used in investing activities of $342.6 million was primarily comprised of purchases of marketable securities of $1,058.9 million and purchases of property and equipment of $7.7 million, offset by cash provided by maturities of marketable securities of $724.0 million.

During the year ended December 31, 2022, cash used in investing activities of $24.1 million was primarily comprised of purchases of marketable securities of $612.8 million and purchases of property and equipment of $10.8 million, offset by cash provided by maturities of marketable securities of $599.5 million.

During the year ended December 31, 2021, cash used in investing activities of $142.1 million was primarily comprised of purchases of marketable securities of $671.3 million and purchases of property and equipment of $6.5 million, offset by cash provided by maturities of marketable securities of $526.8 million and sale of marketable securities of $9.0 million.

95

Cash provided by financing activities

During the year ended December 31, 2023, cash provided by financing activities of $1,229.2 million was comprised of $840.8 million of cash, cash equivalents and restricted cash acquired, net of $20.7 million transaction costs in connection with the EQRx Acquisition, $323.7 million in net proceeds from the March 2023 underwritten public offering, $62.1 million in net proceeds from the issuance of common stock under the ATM, $3.3 million in proceeds from the issuance of common stock under the employee stock purchase plan and $3.3 million in proceeds from the issuance of common stock upon the exercise of stock options, offset by $4.0 million in tax payments in satisfaction of withholding tax requirements pursuant to the EQRx Acquisition.

During the year ended December 31, 2022, cash provided by financing activities of $301.4 million was comprised of $248.1 million in net proceeds from the July 2022 underwritten public offering, $49.9 million in net proceeds from the issuance of common stock under the ATM, $1.9 million in proceeds from the issuance of common stock under the employee stock purchase plan and $1.5 million in proceeds from the issuance of common stock upon the exercise of stock options.

During the year ended December 31, 2021, cash provided by financing activities of $294.2 million was comprised of $281.1 million in net proceeds from the issuance of common stock related from the February 2021 underwritten public offering, $10.1 million in net proceeds from the issuance of common stock under the ATM, $1.9 million in proceeds from the issuance of common stock under the employee stock purchase plan and $1.5 million in proceeds from the issuance of common stock upon the exercise of stock options.

Contractual obligations and commitments

We have contractual obligations related to office and laboratory space leases in Redwood City, California, described in “Note 7. Commitments and contingencies” in the “Notes to Consolidated Financial Statements” contained in Part II, Item 8 of this Annual Report on Form 10-K.

We enter into agreements in the ordinary course of business with contract research organizations for clinical trials, contract manufacturing organizations to provide clinical trial materials and with vendors for preclinical studies and other services and products for operating purposes which are generally cancelable at any time by us upon 30 to 90 days prior written notice.

Indemnification agreements

We enter into standard indemnification arrangements in the ordinary course of business. Pursuant to these arrangements, we indemnify, hold harmless and agree to reimburse the indemnified parties for losses suffered or incurred by the indemnified party, in connection with any trade secret, copyright, patent or other intellectual property infringement claim by any third party with respect to its technology. The term of these indemnification agreements is generally perpetual any time after the execution of the agreement. The maximum potential amount of future payments we could be required to make under these arrangements is not determinable. We have never incurred costs to defend lawsuits or settle claims related to these indemnification agreements. As a result, we believe the fair value of these agreements is minimal.

Critical accounting policies, significant judgments and use of estimate

Our management’s discussion and analysis of our financial condition and results of operations is based on our consolidated financial statements, which have been prepared in accordance with United States generally accepted accounting principles (U.S. GAAP). The preparation of these consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements, as well as the reported expenses incurred during the reporting periods. Our estimates are based on our historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. We believe that the accounting policies discussed below are critical to understanding our historical and future performance, as these policies relate to the more significant areas involving management’s judgments and estimates.

Revenue recognition

We recognize revenue in accordance with Accounting Standards Codification Topic 606, Revenue from Contracts with Customers (ASC 606). Under ASC 606, an entity recognizes revenue when its customer obtains control of promised goods or services, in an amount that reflects the consideration which such entity expects to receive in exchange for those goods or services. In determining the appropriate amount of revenue to be recognized as we fulfill our obligations under arrangements, we perform the following steps: (i) identify the contract(s) with a customer, (ii) identify the performance obligations in the contract, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations in the contract, and (v) recognize revenue when (or

96

as) the entity satisfies the performance obligation. At contract inception, once the contract is determined to be within the scope of ASC 606, we assess the goods or services promised within each contract and determine those that are performance obligations and assess whether each promised good or service is distinct. We then recognize as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied.

We enter into collaboration agreements under which we may obtain upfront license fees, research and development funding, and development, regulatory and commercial milestone payments and royalty payments. Our performance obligations under these arrangements may include licenses of intellectual property, sales and distribution rights, research and development services, delivery of manufactured product and/or participation on joint steering committees.

Licenses of intellectual property: If the license to our intellectual property is determined to be distinct from the other performance obligations identified in the arrangement, we recognize revenue from upfront license fees allocated to the license when the license is transferred to the customer and the customer is able to use and benefit from the license. For licenses that are bundled with other promises, we utilize judgment to assess the nature of the combined performance obligation to determine whether the combined performance obligation is satisfied over time or at a point in time and, if over time, the appropriate method of measuring proportional performance for purposes of recognizing revenue from non-refundable, upfront fees. We evaluate the measure of proportional performance each reporting period and, if necessary, adjust the measure of performance and related revenue recognition.

Research, development and regulatory milestone payments: At the inception of each arrangement that includes research, development, or regulatory milestone payments, we evaluate whether the milestones are considered probable of being reached and estimate the amount to be included in the transaction price. We use the most likely amount method for research, development and regulatory milestone payments. Under the most likely amount method, an entity considers the single most likely amount in a range of possible consideration amounts. If it is probable that a significant revenue reversal would not occur, the associated milestone value is included in the transaction price.

Sales-based milestones and royalties: For arrangements that include sales-based milestone or royalty payments based on the level of sales, and in which the license is deemed to be the predominant item to which the sales-based milestone or royalties relate to, we recognize revenue in the period in which the sales-based milestone is achieved and in the period in which the sales associated with the royalty occur. To date, we have not recognized any sales-based milestone or royalty revenue resulting from our collaboration arrangements.

The transaction price for each collaboration agreement is determined based on the amount of consideration we expect to be entitled for satisfying all performance obligations within the agreement. Significant judgment may be required in determining the amount of variable consideration to be included in the transaction price. We use the most likely amount method to determine variable consideration and will re-evaluate the transaction price in each reporting period and as uncertain events are resolved or other changes in circumstances occur.

Revenue is recognized based on actual costs incurred as a percentage of total estimated costs to be incurred over the performance obligation as we fulfill our performance obligations. A cost-based input method of revenue recognition requires management to make estimates of costs to complete our performance obligations. In making such estimates, significant judgment is required to evaluate assumptions related to cost estimates. The cumulative effect of revisions to estimated costs to fulfill our performance obligations will be recorded in the period in which changes are identified and amounts can be reasonably estimated.

Accrued research and development expenses

We record accrued expenses for estimated preclinical studies and clinical trial expenses. Estimates are based on the services performed pursuant to contracts with research institutions and contract research organizations and clinical manufacturing organizations that conduct and manage preclinical studies and clinical trials on our behalf based on actual time and expenses incurred by them. Further, we accrue expenses related to clinical trials based on the level of patient enrollment and activity according to the related agreement. We monitor patient enrollment levels and related activity to the extent reasonably possible and make judgments and estimates in determining the accrued balance in each reporting period. If we underestimate or overestimate the level of services performed or the costs of these services, our actual expenses could differ from our estimates. To date, we have not experienced significant changes in our estimates of preclinical studies and clinical trial accruals.

Stock-based compensation

We maintain an equity incentive plan as a long-term incentive for employees, consultants and members of our board of directors. The plan allows for the issuance of non-statutory options (NSOs), incentive stock options (ISOs), restricted stock unit awards (RSUs )to employees and NSOs and RSUs to nonemployees.

97

Stock-based compensation is measured using estimated grant date fair value and recognized as compensation expense over the service period in which the awards are expected to vest. The grant date fair value of an RSU award is based on our stock price on the date of grant. For options, we estimate the grant date fair value, and the resulting stock-based compensation, using the Black-Scholes option-pricing model, and we use the straight-line method for expense attribution. The Black-Scholes model requires us to make assumptions and judgments about the variables used in the calculations, including the expected term (weighted-average period of time that the options granted are expected to be outstanding), the expected volatility of our common stock, the related risk-free interest rate and the expected dividend. We have elected to recognize forfeitures of stock-based awards as they occur.

The Black-Scholes option-pricing model requires the use of highly subjective assumptions to determine the fair value of stock-based awards. These assumptions include:

•
Expected Term—The expected term is calculated using the simplified method, which is available where there is insufficient historical data about exercise patterns and post-vesting employment termination behavior. The simplified method is based on the vesting period and the contractual term for each grant, or for each vesting-tranche for awards with graded vesting. The mid-point between the vesting date and the maximum contractual expiration date is used as the expected term under this method.

•
Expected Volatility—Given that we do not have sufficient trading history for our common stock, the expected volatility was estimated based on the average volatility of the Company and comparable publicly traded biotechnology companies over a period equal to the expected term of the stock option grants. The comparable companies were chosen based on their similar size, stage in the life cycle or area of specialty.

•
Risk-Free Interest Rate—The risk-free interest rate is based on the U.S. Treasury zero coupon issues in effect at the time of grant for periods corresponding with the expected term of the option.

•
Expected Dividend—We have never paid dividends on our common stock and have no plans to pay dividends on our common stock. Therefore, we used an expected dividend yield of zero.

Recent accounting pronouncements

For a description of the expected impact of recent accounting pronouncements, see “Note 2. Summary of significant accounting policies” in the “Notes to Consolidated Financial Statements” contained in Part II, Item 8 of this Annual Report on Form 10-K.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

You should read the following discussion and analysis of our financial condition and results of operations in conjunction with the consolidated financial statements and the related notes included elsewhere in this Annual Report on Form 10-K. In addition to historical financial information, this discussion contains forward-looking statements based upon current expectations that involve risks and uncertainties. As a result of many factors, including those factors set forth in the “Risk Factors” section of this Annual Report on Form 10-K, our actual results could differ materially from the results described or implied by the forward-looking statements contained in the following discussion and analysis.

Overview

We are a clinical-stage precision oncology company focused on developing targeted therapies to inhibit frontier targets in RAS-addicted cancers. We possess sophisticated structure-based drug discovery capabilities built upon deep chemical biology and cancer pharmacology know-how and innovative, proprietary technologies that enable the creation of small molecules tailored to unconventional binding sites. Our understanding of genetic drivers and adaptive resistance mechanisms in cancer, coupled with robust drug discovery and medicinal chemistry capabilities, has guided us to establish a deep pipeline targeting critical signaling nodes within the RAS pathway and associated pathways. This cohesive approach underpins our clinical strategy of exploring mechanism-based dosing paradigms and in-pathway combinations to optimize treatment for cancer patients.

Our research and development pipeline comprises RAS(ON) inhibitors that bind directly to RAS variants, which we refer to as RAS(ON) Inhibitors, and RAS companion inhibitors that target key nodes in the RAS pathway or associated pathways, which we refer to as RAS Companion Inhibitors. Our RAS Companion Inhibitors (e.g., SHP2, mTORC1 and SOS1 inhibitors) are designed primarily for combination treatment strategies involving one or more therapeutic agents, which may include our RAS(ON) Inhibitors. Our long-term goal is to combine our RAS(ON) Inhibitors with selected RAS Companion Inhibitors or other therapies on behalf of patients based on molecular tumor features.

RAS (ON) Inhibitors

Our RAS(ON) Inhibitors are based on our proprietary tri-complex technology platform, which enables a highly differentiated approach to inhibiting the active, GTP-bound form of RAS, which we refer to as RAS(ON). We are developing a portfolio of compounds that we believe are the first and only RAS(ON) Inhibitors to use this mechanism of action. We believe that direct inhibitors of RAS(ON) will suppress cell growth and survival and be less susceptible to adaptive resistance mechanisms recognized for RAS(OFF) Inhibitors. We plan to evaluate our RAS(ON) Inhibitors alone and in combination with other drugs and investigational drug candidates, particularly in-pathway agents.

We currently consider three development-stage candidates as the first wave of RAS(ON) Inhibitors that we are advancing:

RMC-6236

RMC-6236, our RASMULTI(ON) Inhibitor, is designed as a first-in-class, potent, oral, RAS-selective tri-complex inhibitor of multiple RAS(ON) variants including cancer drivers at all three of the major mutation hotspot positions, G12, G13, and Q61. RMC-6236 inhibits all three major RAS isoforms, suppressing the mutant cancer driver and cooperating wild-type RAS proteins.

A monotherapy dose-escalation study of RMC-6236 is ongoing and, based on early observations from this study, we believe that RMC-6236 is orally bioavailable and has achieved dose-dependent exposures in patients that are consistent with our preclinical projections. The compound has been generally well-tolerated, including at dose levels at which we have observed clear signals of anti-tumor activity. We continue in dose escalation and we currently expect to provide additional evidence of first-in-class single agent activity for this compound in mid-2023.

RMC-6291

RMC-6291 is designed as a first-in-class, potent, oral and selective tri-complex inhibitor of KRASG12C(ON). It is designed to exhibit subnanomolar potency for suppressing RAS pathway signaling and growth of KRASG12C-bearing cancer cells and is engineered to be highly selective for KRASG12C over wild type RAS and other cellular targets. RMC-6291 is designed to be differentiated from first-generation KRASG12C(OFF) inhibitors, which sequester the KRASG12C(OFF) form, by its mechanism of directly inhibiting the KRASG12C(ON) form.

A monotherapy dose-escalation study of RMC-6291 is ongoing and, based on early observations from this study, we believe that RMC-6291 is orally bioavailable in patients, that it is exhibiting pharmacokinetics consistent with our expectations based on preclinical experiments and that we are dosing the compound in a pharmacologically active range with acceptable safety and tolerability. We currently expect to provide preliminary evidence of a superior profile for this compound in the second half of 2023.

79

RMC-9805

RMC-9805 is designed as a first-in-class, potent, oral and selective, tri-complex inhibitor of KRASG12D(ON). It is designed to exhibit low nanomolar potency for suppressing RAS pathway signaling and growth of KRASG12D-bearing cancer cells and is engineered to covalently inactivate KRASG12D irreversibly. We currently expect to announce dosing of the first patient in a monotherapy dose-escalation study of this compound in mid-2023.

Additional RAS(ON) Inhibitors

Beyond this first wave of RAS(ON) Inhibitors, we have other RAS(ON) Inhibitor compounds currently in our research and development pipeline, including our development candidate RMC-8839, which is designed as a first-in-class, potent, oral and selective, covalent tri-complex inhibitor of KRASG13C(ON) and RMC-0708, which is designed as a first-in-class, potent, oral and selective, non-covalent tri-complex inhibitor of KRASQ61H(ON). RMC-8839 is designed to exhibit picomolar potency for suppressing RAS pathway signaling and growth of KRASG13C-bearing cancer cells and is engineered to covalently inactivate KRASG13C for irreversible inhibition. RMC-0708 is designed to exhibit picomolar potency for suppressing RAS pathway signaling and growth of KRASQ61H-bearing cancer cells and is engineered for selective inhibition of KRASQ61H over other RAS isoforms via non-covalent binding interactions. We are pursuing pipeline expansion programs focused on KRASG12R, KRASG12V, KRASG13D, RASQ61X and other targets.

RAS Companion Inhibitors

RMC-4630

Our RAS Companion Inhibitor RMC-4630 is designed as a potent and selective inhibitor of SHP2, a central node in the RAS signaling pathway. RMC-4630 is being evaluated in a Phase 1/2 clinical program. In 2018, we entered into a collaborative research, development and commercialization agreement with Aventis, Inc. (an affiliate of Sanofi) (the Sanofi Agreement) with respect to SHP2 inhibitors, including RMC-4630. The Sanofi Agreement has been terminated effective as of June 2023, and following the effectiveness of termination, we will regain all global rights granted under the Sanofi Agreement (except as necessary to permit Sanofi to perform any surviving obligations under the Sanofi Agreement), including decision-making regarding research and development, and rights to all commercial proceeds, from RMC-4630.

Our highest priority hypothesis regarding RMC-4630 is that it can deliver additional clinical benefit to patients with RAS-addicted tumors treated with a RAS inhibitor. Below is a list of the clinical studies of RMC-4630 in combination with RAS inhibitors:

•
an Amgen-sponsored Phase 1b study of RMC-4630 in combination with Amgen’s KRASG12C(OFF) inhibitor, sotorasib (LUMAKRAS(R));

•
RMC-4630-03, a Phase 2 study of RMC-4630 in combination with sotorasib that we are sponsoring under a clinical trial collaboration and supply agreement with Amgen; and

•
a Sanofi-sponsored Phase 1/2 study of RMC-4630 in combination with Mirati Therapeutics’ KRASG12C(OFF) inhibitor, adagrasib (KRAZATI(R)).

Amgen is currently evaluating RMC-4630 in a Phase 1b study in combination with Amgen’s KRASG12C(OFF) agent sotorasib in Amgen’s CodeBreaK 101c study. In August 2022, Amgen reported results from this study at the 2022 World Conference on Lung Cancer.

As a complement to the CodeBreaK 101c study, we are sponsoring RMC-4630-03, which is an additional global Phase 2 study of RMC-4630 in combination with sotorasib for patients with non-small cell lung cancer (NSCLC) carrying a KRASG12C mutation who have failed prior standard therapy and who have not previously been treated with a RAS inhibitor. We are sponsoring the RMC-4630-03 study under our global partnership with Sanofi and conducting the trial in collaboration with Amgen, which is supplying sotorasib globally under a clinical collaboration and supply agreement. We currently plan to provide topline data from this study in the second half of 2023.

Sanofi has sponsored a combination study under the Sanofi Agreement and under a clinical trial collaboration and supply agreement between Sanofi and Mirati to evaluate RMC-4630 (also known as SAR442720) in combination with Mirati’s KRASG12C(OFF) inhibitor, adagrasib. We expect that this study will be wound down in connection with the termination of the Sanofi Agreement.

80

There are also several clinical studies of RMC-4630 that do not involve combinations with RAS inhibitors:

•
RMC-4630-01, a Phase 1 study of RMC-4630 as monotherapy;

•
a Sanofi-sponsored Phase 1/2 study of RMC-4630 in combination with the PD-1 inhibitor pembrolizumab (Keytruda®), which we expect will be wound down in connection with the termination of the Sanofi Agreement and

•
a combination of RMC-4630 with an ERK inhibitor in patients with pancreatic cancer as part of an investigator-sponsored study by Netherlands Cancer Institute.

RMC-5552

Our RAS Companion Inhibitor RMC-5552 is designed as a selective inhibitor of hyperactivated mTORC1 signaling in tumors. We are evaluating RMC-5552 first as a monotherapy in a Phase 1 study (RMC-5552-001), and plan to evaluate RMC-5552 in combination with RAS inhibitors for patients with cancers harboring a RAS mutation and co-occurring mutations in the mTOR signaling pathway.

We have reported initial findings from the ongoing dose escalation portion of the RMC-5552-001 study and currently expect to provide additional evidence of single agent activity for this compound in 2023.

We have agreed to supply RMC-5552 to the Regents of the University of California on behalf of its San Francisco campus (UCSF) for an investigator-initiated Phase 1/1b trial by UCSF of RMC-5552 in patients with recurrent glioblastoma.

RMC-5845

Our RAS Companion Inhibitor RMC-5845 targets SOS1, a protein that plays a key role in converting RAS(OFF) to RAS(ON) in cells. RMC-5845 is intended for select combination therapies for certain genetically-defined tumors. This compound is ready for preparation of an IND based on our preclinical development. We continue to evaluate whether to advance RMC-5845 into clinical development in the context of other assets in our portfolio.

RMC-6236

Our RASMULTI(ON) Inhibitor, RMC-6236, is designed to inhibit essentially all RAS(ON) proteins, including normal or wild-type RAS proteins that may help augment oncogenic signaling to tumor cells that have a mutant RAS as a primary driver. Given this broad activity of RMC-6236, we believe it may also be useful as a RAS Companion Inhibitor and we may evaluate the potential benefit from combining RMC-6236 with a RAS inhibitor, including with a RAS(ON) mutant-selective inhibitor such as RMC-6291.

Collaboration agreement with Sanofi

In June 2018, we entered into the Sanofi Agreement with Aventis, Inc. (an affiliate of Sanofi) to research and develop SHP2 inhibitors, including RMC-4630, for any indications. The Sanofi Agreement was assigned to Genzyme Corporation, a Sanofi affiliate, in December 2018. For the purposes of this discussion, we refer to Genzyme Corporation as Sanofi. In December 2022, the Sanofi Agreement was terminated effective as of June 2023, and all rights and obligations described below will terminate and revert to us upon effectiveness of this termination, except as necessary to permit Sanofi to perform any surviving obligations under the Sanofi Agreement

Pursuant to the Sanofi Agreement, we granted Sanofi a worldwide, exclusive, sublicensable (subject to our consent in certain circumstances) license under certain of our patents and know-how to research, develop, manufacture, use, sell, offer for sale, import and otherwise commercialize SHP2 inhibitors, including RMC-4630, for any and all uses, subject to our exercise of rights and performance of obligations under the Sanofi Agreement. Such intellectual property exclusively licensed to Sanofi includes our interest under any of our solely-owned or jointly-owned inventions arising out of activities undertaken pursuant to the development of SHP2 inhibitor product candidates under the Sanofi Agreement.

Under the Sanofi Agreement, we have primary responsibility for early clinical development of RMC-4630 pursuant to an approved development plan. Sanofi is responsible to reimburse us for all internal and external costs and expenses to perform our activities under approved development plans, except for costs and expenses related to studies designated in the Sanofi Agreement as RevMed Studies, for which we will bear all costs and expenses, and for the RMC-4630-03 study, for which we have agreed that Sanofi will reimburse us for 50% of the costs and expenses. Unreimbursed costs borne by us for any RevMed Studies and for our 50% share of the RMC-4630-03 collaboration study are subject to future reimbursement by Sanofi through a buy-in payment pursuant to the terms of the Sanofi Agreement if they use data from a RevMed Study or the RMC-4630-03 study in support of a marketing approval application. There currently are no active RevMed Studies.

81

We are responsible for the manufacture of SHP2 inhibitors for Phase 1 and non-registrational Phase 2 clinical trials pursuant to an approved development plan, while Sanofi is responsible for manufacturing SHP2 inhibitors for all other clinical trials and commercial supply. Sanofi has the sole right and responsibility to perform all regulatory activities under the Sanofi Agreement, except with respect to certain trials conducted by us or otherwise conducted under our IND, including our current clinical trials evaluating RMC-4630.

Unless otherwise delegated to us by the joint commercialization committee, during the term of the Sanofi Agreement, Sanofi also has the sole right and responsibility for all aspects of the commercialization of SHP2 inhibitors in the world for any and all uses, at its expense, subject to our right to elect to co-promote SHP2 inhibitors in the United States. Sanofi agrees to provide us, and we agree to provide Sanofi, with research, development and commercialization updates through the joint committees.

During the term of the Sanofi Agreement, we may not, alone or with any affiliate or third party, conduct certain research activities with respect to, or develop or commercialize, any product that contains a SHP2 inhibitor outside of the Sanofi Agreement.

Pursuant to the Sanofi Agreement, we received an upfront payment of $50 million from Sanofi in July 2018. The Sanofi Agreement includes obligations for Sanofi to make certain milestone payments and royalty payments, all of which will expire upon effectiveness of termination of the Sanofi Agreement.

During the term of the Sanofi Agreement, Sanofi has the sole and exclusive right to file, prosecute and maintain any patents licensed to it pursuant to the Sanofi Agreement, as well as to enforce infringement of or defend claims against such patents that relate to SHP2 inhibitor products.

Upon effectiveness of the termination of the Sanofi Agreement, the licenses granted to Sanofi thereunder shall become fully paid-up, royalty-free, perpetual and irrevocable and all rights and obligations of Sanofi under the Sanofi Agreement will revert to us.

Through December 31, 2022, we have received an aggregate of $176.9 million from Sanofi, including the upfront payment and research and development expense reimbursements.

Financial Operations Overview

Collaboration revenue

Collaboration revenue consists of revenue under the Sanofi Agreement for our SHP2 program. We received a $50.0 million upfront payment from Sanofi in July 2018 and receive reimbursement for research and development services. The Sanofi Agreement is expected to terminate in June 2023.

For further information on our revenue recognition policies, see “Note 2. Summary of significant accounting policies” in the “Notes to Consolidated Financial Statements” contained in Part II, Item 8 of this Annual Report on Form 10-K.

Research and development expenses

We substantially rely on third parties to conduct our preclinical studies, clinical trials and manufacturing. We estimate research and development expenses based on estimates of services performed, and rely on third party contractors and vendors to provide us with timely and accurate estimates of expenses of services performed to assist us in these estimates. Research and development expenses consist primarily of costs incurred for the development of our product candidates and costs associated with identifying compounds through our discovery platform, which include:

•
expenses incurred under agreements with third-party contract organizations, investigative clinical trial sites that conduct research and development activities on our behalf and consultants;

•
costs related to production of clinical and preclinical materials, including fees paid to contract manufacturers;

•
laboratory and vendor expenses related to the execution of discovery programs, preclinical and clinical trials;

•
employee-related expenses, which include salaries, benefits and stock-based compensation; and

•
facilities and other expenses, which include allocated expenses for rent and maintenance of facilities, depreciation and amortization expense, information technology and other supplies.

82

We expense all research and development costs in the periods in which they are incurred. Costs for certain development activities are recognized based on an evaluation of the progress to completion of specific tasks using information and data provided to us by our vendors, collaborators and third-party service providers. Nonrefundable advance payments for goods or services to be received in future periods for use in research and development activities are deferred and recorded as prepaid assets. The prepaid amounts are then expensed as the related goods are delivered or as services are performed.

Up to the termination date of the Sanofi Agreement, Sanofi is responsible to reimburse us for all internal and external costs and expenses to perform our activities under approved development plans, except for 50% of the RMC-4630-03 study. These reimbursements from Sanofi are recorded as collaboration revenue.

We expect our research and development expenses to increase for the foreseeable future as we continue to invest in discovering and developing product candidates and advancing product candidates into later stages of development, which may include conducting larger clinical trials. The process of conducting the necessary research and development and clinical trials to seek regulatory approval for product candidates is costly and time-consuming, and the successful development of our product candidates is highly uncertain. As a result, we are unable to determine the duration and completion costs of our research and development projects or clinical trials or if and to what extent we will generate revenue from the commercialization and sale of any of our product candidates.

General and administrative expenses

General and administrative expenses consist primarily of personnel-related costs, consultants and professional services expenses, including legal, audit, accounting and human resources services, insurance, allocated facilities and information technology costs, and other general operating expenses not otherwise classified as research and development expenses. Personnel-related costs consist of salaries, benefits and stock-based compensation. Facilities costs consist of rent, utilities and maintenance of facilities. We expect our general and administrative expenses to increase for the foreseeable future due to anticipated increases in headcount and as a result of operating as a public company, including expenses related to compliance with the rules and regulations of the Securities and Exchange Commission, the Nasdaq Global Select Market, investor relations activities and other administrative and professional services.

Interest income

Interest income primarily consists of interest earned on and accretion of our cash equivalents and marketable securities.

Interest expense

Interest expense primarily consists of interest related to our finance lease and interest on other outstanding obligations.

Benefit from income taxes

Benefit from income taxes relates to net changes in the deferred tax liability associated with our Warp Drive acquisition resulting from changes in the effective state tax rate and changes in our valuation allowance.

Results of operations

Comparison of the years ended December 31, 2022 and 2021

Collaboration revenue

Collaboration revenue consists of revenue under the Sanofi Agreement, which is expected to terminate in 2023. As a result of the expected termination of the agreement and development plan adjustments during the year, we revised our estimate of the accounting transaction price and increased our percentage of completion under the agreements with Sanofi, which resulted in total cumulative catch-up adjustments that increased collaboration revenue by $3.0 million for the year ended December 31, 2022.

In August 2021, we entered into a Letter Agreement with Sanofi to include RMC-4630-03 under the development plan for RMC-4630 and decided to no longer enroll new patients in RMC-4630-02. As a result of these development plan adjustments, we revised the estimate of the accounting transaction price and decreased our estimated percentage of completion under the agreements with Sanofi, and resulted in a cumulative catch-up adjustment that reduced collaboration revenue by $8.5 million for the year ended December 31, 2021.

Collaboration revenue increased by $6.0 million, or 20%, during the year ended December 31, 2022 compared to the same period in 2021. The increase was due to the cumulative catch-up adjustments resulting from the Sanofi Agreement termination and development plan adjustments, partially offset by lower reimbursable SHP2 program research and development costs under the Sanofi Agreement for the year ended December 31, 2022.

Research and development expenses

Research and development expenses increased by $66.1 million, or 35%, during the year ended December 31, 2022 compared to the same period in 2021. The increase in research and development expenses during the year ended December 31, 2022 was primarily due to a $16.1 million increase in third-party costs for our preclinical research portfolio, primarily driven by higher chemistry contract research organization, material sourcing and manufacturing costs; a $16.1 million increase in salaries and other employee-related expenses due to increased headcount to support our research and development programs; a $14.8 million increase in RMC-6236 costs, which commenced clinical trials in the second quarter of 2022; a $10.2 million increase in facilities and other allocated expenses as a result of higher rent, utilities and information technology expenses associated with increased headcount; a $6.3 million increase in stock-based compensation; and a $5.2 million increase in RMC-6291 costs, which commenced clinical trials in the third quarter of 2022.

84

General and administrative expenses

General and administrative expenses increased by $10.1 million, or 33%, during the year ended December 31, 2022 compared to the same period in 2021. The increase in general and administrative expenses during the year ended December 31, 2022 was primarily due to an increase of $4.2 million in stock-based compensation expense; an increase of $3.9 million in salaries and other employee-related expenses due to increased headcount; a $0.7 million increase in facilities and other allocated expenses as a result of higher rent, utilities and information technology expenses associated with increased headcount; and a $0.8 million increase in legal and accounting fees.

Interest income

Interest income increased by $8.2 million for the year ended December 31, 2022, compared to the same period in 2021 due to a larger cash, cash equivalents and marketable securities balance and higher interest rates.

Interest expense

Interest expense was zero for the year ended December 31, 2022 and less than $0.1 million for the year ended December 31, 2021.

Benefit from income taxes

Benefit from income taxes was $0.4 million for the year ended December 31, 2022 and zero for the year ended December 31, 2021 and related to net changes in the valuation allowance resulting from the Warp Drive acquisition.

Comparison of the years ended December 31, 2021 and 2020

Collaboration revenue

In August 2021, we entered into a Letter Agreement with Sanofi to include RMC-4630-03 under the development plan for RMC-4630 and ceased enrollment of new patients in RMC-4630-02. As a result of these development plan adjustments, we revised our estimate of the accounting transaction price and our percentage of completion under the agreements with Sanofi, which resulted in a cumulative catch-up adjustment that reduced collaboration revenue by $8.5 million for the year ended December 31, 2021.

Collaboration revenue decreased by $13.6 million, or 32%, during the year ended December 31, 2021 compared to the same period in 2020. The decreases in collaboration revenue during the year ended December 31, 2021 was primarily due to the cumulative catch-up adjustment and lower reimbursed manufacturing costs.

Research and development expenses

Research and development expenses increased by $54.7 million, or 41%, during the year ended December 31, 2021 compared to the same period in 2020. The increase in research and development expenses during the year ended December 31, 2021 was primarily

85

due to a $34.5 million increase in third-party costs for our preclinical research portfolio, primarily driven by higher chemistry contract research organization, material sourcing and manufacturing costs; a $9.2 million increase in salaries and other employee-related expenses due to increased headcount to support our research and development programs, a $7.0 million increase in stock-based compensation, and a $5.4 million increase in facilities and other allocated expenses as a result of higher rent, utilities and information technology expenses associated with increased headcount.

General and administrative expenses

General and administrative expenses increased by $9.0 million, or 42%, during the year ended December 31, 2021 compared to the same period in 2020. The increase in general and administrative expenses during the year ended December 31, 2021 was primarily due to an increase of $4.8 million in stock-based compensation expense; an increase of $2.3 million in salaries and other employee-related expenses due to increased headcount; and an increase of $0.8 million in insurance.

Interest income

Interest income decreased by $1.3 million for the year ended December 31, 2021, compared to the same period in 2020 due to lower interest rates.

Interest expense

Interest expense was less than $0.1 million for both years ended December 31, 2021 and 2020.

Benefit from income taxes

Benefit from income taxes was zero for the year ended December 31, 2021 and $0.4 million for the year ended December 31, 2020 and related to net changes in the valuation allowance resulting from the Warp Drive acquisition.

Liquidity and capital resources

In February 2020, we closed our IPO and issued 16,100,000 shares of our common stock at a price to the public of $17.00 per share for net proceeds of approximately $250.7 million, after deducting underwriting discounts and commissions of $19.2 million and expenses of $3.8 million.

In July 2020, we issued 6,900,000 shares of our common stock in an underwritten public offering at a price to the public of $26.00 per share for net proceeds of $167.8 million, after deducting underwriting discounts and commissions of $10.8 million and offering expenses of $0.8 million.

In February 2021, we issued 6,666,666 shares of our common stock in an underwritten public offering at a price to the public of $45.00 per share for net proceeds of $281.1 million, after deducting underwriting discounts and commissions of $18.0 million and offering expenses of $0.9 million.

In November 2021, we entered into a sales agreement with Cowen and Company, LLC (Cowen) to sell shares of our common stock, from time to time, with aggregate gross proceeds of up to $250 million, through an at-the-market equity offering program (ATM) under which Cowen agreed to act as our sales agent. In 2021, we sold an aggregate of 339,302 shares of common stock under the ATM resulting in gross proceeds to us of $10.4 million. After deducting commissions and expenses of $0.3 million, net proceeds to us were $10.1 million.

In July 2022, we issued 13,225,000 shares of our common stock in an underwritten public offering at a price to the public of $20.00 per share, for net proceeds of $248.1 million, after deducting underwriting discounts and commissions of $15.9 million and estimated offering expenses of $0.5 million.

During the year ended December 31, 2022, we sold an aggregate of 2,385,846 shares of common stock under the ATM resulting in gross proceeds of $51.3 million. After deducting commissions and expenses of $1.4 million, our net proceeds under the ATM were $49.9 million.

Our operations have been financed primarily by our public offerings of common stock, net proceeds of $230.6 million from the issuance of our preferred stock and $176.9 million received under the Sanofi Agreement for upfront payments and for research and development cost reimbursement.

As of December 31, 2022, we had $644.9 million in cash, cash equivalents and marketable securities.

86

As of December 31, 2022, we had an accumulated deficit of $701.3 million. Our primary use of cash is to fund operating expenses, which consist primarily of research and development expenditures related to our product candidates and our preclinical research portfolio, and to a lesser extent, general and administrative expenditures. We expect our expenses to continue to increase in connection with our ongoing activities, particularly as we continue to advance our product candidates and preclinical research portfolio.

We believe that our existing cash, cash equivalents and marketable securities will enable us to fund our planned operations for at least 12 months following the date of this report.

The timing and amount of our future funding requirements depends on many factors, including:

•
the scope, progress, results and costs of researching and developing our product candidates and programs, and of conducting preclinical studies and clinical trials;

•
the timing of, and the costs involved in, obtaining marketing approvals for product candidates we develop if clinical trials are successful;

•
the successful wind-up of our collaboration with Sanofi, which has been terminated effective as of June 2023, including the continued reimbursement by Sanofi of our research and development costs for our SHP2 program in accordance with the Sanofi Agreement prior to the effectiveness of termination;

•
the cost of commercialization activities for any product candidates we develop, whether alone or in collaboration, including marketing, sales and distribution costs if any product candidate we develop is approved for sale;

•
the cost of manufacturing our current and future product candidates for clinical trials in preparation for marketing approval and in preparation for commercialization;

•
our ability to establish and maintain strategic licenses or other arrangements and the financial terms of such agreements;

•
the costs involved in preparing, filing, prosecuting, maintaining, expanding, defending and enforcing patent claims, including litigation costs and the outcome of such litigation;

•
the timing, receipt and amount of sales of, profit share or royalties on, our future products, if any;

•
the emergence of competing cancer therapies or other adverse market developments; and

•
any plans to acquire or in-license other programs or technologies.

We expect to need to obtain substantial additional funding in the future to continue the preclinical and clinical development of our current and future programs and to prepare for their potential commercialization. If we need to raise additional capital to fund our operations, funding may not be available to us on acceptable terms, or at all. If we are unable to obtain adequate financing when needed, we may have to delay, reduce the scope of or suspend one or more of our clinical trials, research and development programs or commercialization efforts. We may seek to raise any necessary additional capital through a combination of public or private equity offerings, debt financings and collaborations or licensing arrangements. If we do raise additional capital through public or private equity offerings, the ownership interest of our existing stockholders will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect our stockholders’ rights. If we raise additional capital through debt financing, we may be subject to covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends, and if the debt is convertible into our common stock, the ownership interest of our stockholders may be diluted. If we are unable to raise capital, we may need to delay, reduce or terminate planned activities to reduce costs. Doing so will likely harm our ability to execute our business plans.

Cash flows

The following table summarizes our consolidated cash flows for the periods indicated:

87

Cash used in operating activities

During the year ended December 31, 2022, cash used in operating activities of $224.4 million was attributable to a net loss of $248.7 million partially offset by $37.8 million in non-cash charges and by a net change of $13.5 million in our operating assets and liabilities. The non-cash charges primarily consisted of stock-based compensation expense of $31.2 million, depreciation and amortization of $5.0 million, amortization of operating lease right-of-use asset of $4.6 million offset by net amortization of premium on marketable securities of $3.1 million. The change in operating assets and liabilities was primarily due to a $3.8 million increase in prepaid expenses and other current assets primarily resulting from the timing of prepayments made for research and development activities, a $14.5 million decrease in deferred revenue associated with the Sanofi Agreement, a $2.4 million decrease in operating lease liability, offset by a $7.3 million increase in accounts payable, $1.5 million increase in accrued expenses and other current liabilities and a $1.3 million decrease in accounts receivable.

During the year ended December 31, 2021, cash used in operating activities of $147.2 million was attributable to a net loss of $187.1 million partially offset by $31.2 million in non-cash charges and by net change of $8.7 million in our operating assets and liabilities. The non-cash charges primarily consisted of stock-based compensation expense of $20.7 million, depreciation and amortization of $4.2 million, net amortization of premium on marketable securities of $3.0 million and amortization of operating lease right-of-use asset of $3.2 million. The change in operating assets and liabilities was primarily due to an $11.0 million increase in accrued expenses and accounts payable partially offset by a $1.7 million decrease in deferred revenue associated with the Sanofi Agreement and a $1.5 million decrease in operating lease liability.

During the year ended December 31, 2020, cash used in operating activities of $100.1 million was attributable to a net loss of $108.2 million and a net change of $8.3 million in our operating assets and liabilities, partially offset by $16.4 million in non-cash charges. The non-cash charges primarily consisted of stock-based compensation expense of $8.9 million, depreciation and amortization of $3.7 million, net amortization of premium on marketable securities of $0.1 million and amortization of operating lease right-of-use asset of $2.9 million. The change in operating assets and liabilities was primarily due to an $11.3 million decrease in deferred revenue associated with the Sanofi Agreement partially offset by a $4.9 million increase in accrued expenses and other current assets.

Cash used in investing activities

During the year ended December 31, 2022, cash used in investing activities of $24.1 million was primarily comprised of purchases of marketable securities of $612.8 million and purchases of property and equipment of $10.8 million, offset by cash provided by maturities of marketable securities of $599.5 million.

Cash provided by financing activities

During the year ended December 31, 2022, cash provided by financing activities of $301.4 million was comprised of $248.1 million in net proceeds from the July 2022 underwritten public offering, $49.9 million in net proceeds from the issuance of common stock under the ATM, $1.9 million in proceeds from the issuance of common stock under the employee stock purchase plan and $1.5 million in proceeds from the issuance of common stock upon the exercise of stock options.

During the year ended December 31, 2021, cash provided by financing activities of $294.2 million was comprised of $281.1 million in net proceeds from the issuance of common stock related from the February 2021 underwritten public offering, $10.1 million in net proceeds from the issuance of common stock under the ATM, $1.9 million in proceeds from the issuance of common stock under the employee stock purchase plan and $ 1.5 million in proceeds from the issuance of common stock upon the exercise of stock options.

During the year ended December 31, 2020, cash provided by financing activities of $422.8 million was comprised of $420.1 million in net proceeds from the issuance of common stock related to our IPO in February 2020 and our underwritten public offering in July 2020, $1.9 million in proceeds from the issuance of common stock upon the exercise of stock options and $0.8 million in proceeds from the issuance of common stock under the employee stock purchase plan.

Contractual obligations and commitments

We have contractual obligations related to office and laboratory space leases in Redwood City, California and Cambridge, Massachusetts, described in “Note 7. Commitments and contingencies” in the “Notes to Consolidated Financial Statements” contained in Part II, Item 8 of this Annual Report on Form 10-K.

We enter into agreements in the ordinary course of business with contract research organizations for clinical trials, contract manufacturing organizations to provide clinical trial materials and with vendors for preclinical studies and other services and products for operating purposes which are generally cancelable at any time by us upon 30 to 90 days prior written notice.

Indemnification agreements

We enter into standard indemnification arrangements in the ordinary course of business. Pursuant to these arrangements, we indemnify, hold harmless and agree to reimburse the indemnified parties for losses suffered or incurred by the indemnified party, in connection with any trade secret, copyright, patent or other intellectual property infringement claim by any third party with respect to its technology. The term of these indemnification agreements is generally perpetual any time after the execution of the agreement. The maximum potential amount of future payments we could be required to make under these arrangements is not determinable. We have never incurred costs to defend lawsuits or settle claims related to these indemnification agreements. As a result, we believe the fair value of these agreements is minimal.

Critical accounting policies, significant judgments and use of estimate

Our management’s discussion and analysis of our financial condition and results of operations is based on our consolidated financial statements, which have been prepared in accordance with United States generally accepted accounting principles (U.S. GAAP). The preparation of these consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements, as well as the reported expenses incurred during the reporting periods. Our estimates are based on our historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. We believe that the accounting policies discussed below are critical to understanding our historical and future performance, as these policies relate to the more significant areas involving management’s judgments and estimates.

Revenue recognition

We recognize revenue is accordance with Accounting Standards Codification Topic 606, Revenue from Contracts with Customers (ASC 606). Under ASC 606, an entity recognizes revenue when its customer obtains control of promised goods or services, in an amount that reflects the consideration which such entity expects to receive in exchange for those goods or services. In determining the appropriate amount of revenue to be recognized as we fulfill our obligations under arrangements, we perform the following steps: (i) identify the contract(s) with a customer, (ii) identify the performance obligations in the contract, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations in the contract, and (v) recognize revenue when (or as) the entity satisfies the performance obligation. At contract inception, once the contract is determined to be within the scope of ASC 606, we assess the goods or services promised within each contract and determine those that are performance obligations and assess whether each promised good or service is distinct. We then recognize as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied.

We enter into collaboration agreements under which we may obtain upfront license fees, research and development funding, and development, regulatory and commercial milestone payments and royalty payments. Our performance obligations under these arrangements may include licenses of intellectual property, sales and distribution rights, research and development services, delivery of manufactured product and/or participation on joint steering committees.

Licenses of intellectual property: If the license to our intellectual property is determined to be distinct from the other performance obligations identified in the arrangement, we recognize revenue from upfront license fees allocated to the license when the license is transferred to the customer and the customer is able to use and benefit from the license. For licenses that are bundled with other promises, we utilize judgment to assess the nature of the combined performance obligation to determine whether the combined performance obligation is satisfied over time or at a point in time and, if over time, the appropriate method of measuring proportional performance for purposes of recognizing revenue from non-refundable, upfront fees. We evaluate the measure of proportional performance each reporting period and, if necessary, adjust the measure of performance and related revenue recognition.

Research, development and regulatory milestone payments: At the inception of each arrangement that includes research, development, or regulatory milestone payments, we evaluate whether the milestones are considered probable of being reached and estimate the amount to be included in the transaction price. We use the most likely amount method for research, development and regulatory milestone payments. Under the most likely amount method, an entity considers the single most likely amount in a range of possible consideration amounts. If it is probable that a significant revenue reversal would not occur, the associated milestone value is included in the transaction price.

Sales-based milestones and royalties: For arrangements that include sales-based milestone or royalty payments based on the level of sales, and in which the license is deemed to be the predominant item to which the sales-based milestone or royalties relate to, we recognize revenue in the period in which the sales-based milestone is achieved and in the period in which the sales associated with the royalty occur. To date, we have not recognized any sales-based milestone or royalty revenue resulting from our collaboration arrangements.

The transaction price for each collaboration agreement is determined based on the amount of consideration we expect to be entitled for satisfying all performance obligations within the agreement. Significant judgment may be required in determining the amount of variable consideration to be included in the transaction price. We use the most likely amount method to determine variable consideration and will re-evaluate the transaction price in each reporting period and as uncertain events are resolved or other changes in circumstances occur.

90

Revenue is recognized based on actual costs incurred as a percentage of total estimated costs to be incurred over the performance obligation as we fulfill our performance obligations. A cost-based input method of revenue recognition requires management to make estimates of costs to complete our performance obligations. In making such estimates, significant judgment is required to evaluate assumptions related to cost estimates. The cumulative effect of revisions to estimated costs to fulfill our performance obligations will be recorded in the period in which changes are identified and amounts can be reasonably estimated.

Accrued research and development expenses

We record accrued expenses for estimated preclinical studies and clinical trial expenses. Estimates are based on the services performed pursuant to contracts with research institutions and contract research organizations and clinical manufacturing organizations that conduct and manage preclinical studies and clinical trials on our behalf based on actual time and expenses incurred by them. Further, we accrue expenses related to clinical trials based on the level of patient enrollment and activity according to the related agreement. We monitor patient enrollment levels and related activity to the extent reasonably possible and make judgments and estimates in determining the accrued balance in each reporting period. If we underestimate or overestimate the level of services performed or the costs of these services, our actual expenses could differ from our estimates. To date, we have not experienced significant changes in our estimates of preclinical studies and clinical trial accruals.

Stock-based compensation

We maintain an equity incentive plan as a long-term incentive for employees, consultants and members of our board of directors. The plan allows for the issuance of non-statutory options, or NSOs, incentive stock options, or ISOs, restricted stock unit awards, or RSUs to employees and NSOs and RSUs to nonemployees.

Stock-based compensation is measured using estimated grant date fair value and recognized as compensation expense over the service period in which the awards are expected to vest. The grant date fair value of an RSU award is based on our stock price on the date of grant. For options, we estimate the grant date fair value, and the resulting stock-based compensation, using the Black-Scholes option-pricing model, and we use the straight-line method for expense attribution. The Black-Scholes model requires us to make assumptions and judgments about the variables used in the calculations, including the expected term (weighted-average period of time that the options granted are expected to be outstanding), the expected volatility of our common stock, the related risk-free interest rate and the expected dividend. We have elected to recognize forfeitures of stock-based awards as they occur.

The Black-Scholes option-pricing model requires the use of highly subjective assumptions to determine the fair value of stock-based awards. These assumptions include:

•
Expected Term—The expected term is calculated using the simplified method, which is available where there is insufficient historical data about exercise patterns and post-vesting employment termination behavior. The simplified method is based on the vesting period and the contractual term for each grant, or for each vesting-tranche for awards with graded vesting. The mid-point between the vesting date and the maximum contractual expiration date is used as the expected term under this method.

•
Expected Volatility—Given that we do not have sufficient trading history for our common stock, the expected volatility was estimated based on the average volatility of the Company and comparable publicly traded biotechnology companies over a period equal to the expected term of the stock option grants. The comparable companies were chosen based on their similar size, stage in the life cycle or area of specialty.

•
Risk-Free Interest Rate—The risk-free interest rate is based on the U.S. Treasury zero coupon issues in effect at the time of grant for periods corresponding with the expected term of the option.

•
Expected Dividend—We have never paid dividends on our common stock and have no plans to pay dividends on our common stock. Therefore, we used an expected dividend yield of zero.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

You should read the following discussion and analysis of our financial condition and results of operations in conjunction with the consolidated financial statements and the related notes included elsewhere in this Annual Report on Form 10-K. In addition to historical financial information, this discussion contains forward-looking statements based upon current expectations that involve risks and uncertainties. As a result of many factors, including those factors set forth in the “Risk Factors” section of this report, our actual results could differ materially from the results described or implied by the forward-looking statements contained in the following discussion and analysis.

Overview

We are a clinical-stage precision oncology company focused on developing targeted therapies to inhibit frontier targets in RAS-addicted cancers. We possess sophisticated structure-based drug discovery capabilities built upon deep chemical biology and cancer pharmacology know-how and innovative, proprietary technologies that enable the creation of small molecules tailored to unconventional binding sites. Our understanding of genetic drivers and adaptive resistance mechanisms in cancer, coupled with robust drug discovery and medicinal chemistry capabilities, has guided us to establish a deep pipeline targeting critical signaling nodes within the RAS pathway and associated pathways. This cohesive approach underpins our clinical strategy of exploring mechanism-based dosing paradigms and in-pathway combinations to optimize treatment for cancer patients.

Our research and development pipeline comprises RAS(ON) inhibitors that bind directly to RAS variants, which we refer to as RAS(ON) Inhibitors, and RAS companion inhibitors that target key nodes in the RAS pathway or associated pathways, which we refer to as RAS Companion Inhibitors. Our RAS Companion Inhibitors (e.g., SHP2, mTORC1 and SOS1 inhibitors) are designed primarily for combination treatment strategies involving one or more therapeutic agents, which may include our RAS(ON) Inhibitors. Our long-term goal is to combine selected RAS Companion Inhibitors with RAS(ON) Inhibitors on behalf of patients based on molecular tumor features.

RAS (ON) Inhibitors

Our RAS(ON) Inhibitors are based on our proprietary tri-complex technology platform, which enables a highly differentiated approach to inhibiting the active, GTP-bound form of RAS, which we refer to as RAS(ON). We are developing a portfolio of compounds that we believe are the first and only RAS(ON) inhibitors to use this mechanism of action. We currently have four RAS(ON) Inhibitors in the IND-enabling stage of preclinical development: RMC-6236, our inhibitor of multiple RAS variants, which we refer to as RASMULTI(ON), RMC-6291, our inhibitor targeting KRASG12C(ON), RMC-9805, our inhibitor targeting KRASG12D(ON) and RMC-8839, our inhibitor targeting KRASG13C(ON). We currently plan to submit an IND for RMC-6236 in the first half of 2022 and to provide evidence of first-in-class single agent activity for this compound in 2023. We currently plan to submit an IND for RMC-6291 in the first half of 2022 and to provide preliminary evidence of superior activity for this compound in 2023. We currently plan to submit an IND for RMC-9805 in the first half of 2023 and to submit an IND for RMC-8839 in the second half of 2023. In addition to the compounds currently in development, we are also focused on developing additional mutant-selective inhibitors.

RAS Companion Inhibitors

RMC-4630

Our RAS Companion Inhibitor RMC-4630 is designed as a potent and selective inhibitor of SHP2, a central node in the RAS signaling pathway. In collaboration with Sanofi, we are evaluating RMC-4630 in a multi-cohort Phase 1/2 clinical program.

Our highest priority hypothesis regarding RMC-4630 is that it can deliver additional clinical benefit to patients with RAS-addicted tumors treated with a RAS inhibitor. Below is a list of the active or planned clinical studies of RMC-4630 in combination with RAS inhibitors:

•
an active Amgen-sponsored Phase 1b study of RMC-4630 in combination with Amgen’s KRASG12C(OFF) inhibitor, sotorasib (LumakrasTM);

•
RMC-4630-03, an active Phase 2 study of RMC-4630 in combination with sotorasib that we are sponsoring under a clinical trial collaboration and supply agreement with Amgen under our global partnership with Sanofi; and

•
the planned Sanofi-sponsored Phase 1/2 study of RMC-4630 in combination with Mirati Therapeutics’ KRASG12C(OFF) inhibitor, adagrasib.

76

Amgen is currently evaluating RMC-4630 in an active Phase 1b study in combination with Amgen’s KRASG12C(OFF) agent sotorasib in Amgen’s CodeBreaK 101c study.

As a complement to the CodeBreaK 101c study, we are sponsoring RMC-4630-03, which is an additional global Phase 2 study of RMC-4630 in combination with sotorasib for patients with non-small cell lung cancer (NSCLC) carrying a KRASG12C mutation who have failed prior standard therapy and who have not previously been treated with a RAS inhibitor. The first patient in RMC-4630-03 has been dosed and enrollment is ongoing. We are sponsoring the RMC-4630-03 study under our global partnership with Sanofi and conducting the trial in collaboration with Amgen, which is supplying sotorasib globally under a clinical collaboration and supply agreement. We expect to complete enrollment in RMC-4630-03 in the second half of 2022, to provide preliminary evidence of the clinical benefit of RMC-4630 as a RAS Companion Inhibitor from the RMC-4630-03 study in the second half of 2022 and to provide additional evidence of the clinical benefit of this compound from this study in 2023.

Sanofi plans to sponsor a combination study under our 2018 collaborative research, development and commercialization agreement with Aventis, Inc. (an affiliate of Sanofi) (the Sanofi Agreement) and under a clinical trial collaboration and supply agreement between Sanofi and Mirati to evaluate RMC-4630 (also known as SAR442720) in combination with Mirati’s KRASG12C(OFF) inhibitor, adagrasib.

There are also several active or planned clinical studies of RMC-4630 that do not involve combinations with RAS inhibitors:

•
RMC-4630-01, an active Phase 1 study of RMC-4630 as monotherapy;

•
a Sanofi-sponsored active Phase 1/2 study of RMC-4630 in combination with the PD-1 inhibitor pembrolizumab (Keytruda®); and

•
a combination of RMC-4630 with an ERK inhibitor in patients with pancreatic cancer as part of an investigator sponsored study planned by Netherlands Cancer Institute.

RMC-5552

Our RAS Companion Inhibitor RMC-5552 is designed as a selective inhibitor of hyperactivated mTORC1 signaling in tumors. We are evaluating RMC-5552 first as a monotherapy in a Phase 1 study (RMC-5552-01), and plan to evaluate RMC-5552 in combination with RAS inhibitors for patients with cancers harboring a RAS mutation and co-occurring mutations in the mTOR signaling pathway.

In January 2022, we reported initial findings from the ongoing dose escalation portion of the RMC-5552-01 study, including preliminary evidence of clinical activity against advanced tumors with mutations associated with hyperactive mTORC1 signaling. As of January 7, 2022, all four efficacy evaluable patients treated with 6 mg per week experienced disease control, including one patient with a confirmed partial response with a 63% reduction from baseline and the other three with stable disease. We currently expect to provide additional evidence of single agent activity for this compound in 2023.

RMC-5845

Our RAS Companion Inhibitor RMC-5845 targets SOS1, a protein that plays a key role in converting RAS(OFF) to RAS(ON) in cells. RMC-5845 is intended for select combination therapies for certain genetically-defined tumors. This compound is ready for preparation of an IND based on the Company’s preclinical development. We continue evaluating the scientific rationale for advancing RMC-5845 into clinical development in the context of other assets in our portfolio.

Collaboration agreement with Sanofi

In June 2018, we entered into the Sanofi Agreement with Aventis, Inc. (an affiliate of Sanofi) to research and develop SHP2 inhibitors, including RMC-4630, for any indications. The Sanofi Agreement was assigned to Genzyme Corporation, a Sanofi affiliate, in December 2018. For the purposes of this discussion, we refer to Genzyme Corporation as Sanofi. Pursuant to the Sanofi Agreement, we granted Sanofi a worldwide, exclusive, sublicensable (subject to our consent in certain circumstances) license under certain of our patents and know-how to research, develop, manufacture, use, sell, offer for sale, import and otherwise commercialize SHP2 inhibitors, including RMC-4630, for any and all uses, subject to our exercise of rights and performance of obligations under the Sanofi Agreement. Such intellectual property exclusively licensed to Sanofi includes our interest under any of our solely-owned or jointly-owned inventions arising out of activities undertaken pursuant to the development of SHP2 inhibitor product candidates under the Sanofi Agreement.

77

Under the Sanofi Agreement, we have primary responsibility for early clinical development of RMC-4630 pursuant to a development plan that is currently approved through 2022. The development plan and budget beyond 2022 will be determined by a joint research and development committee, over which Sanofi has final decision-making power subject to certain exceptions. Sanofi is responsible to reimburse us for all internal and external costs and expenses to perform our activities under approved development plans, except for costs and expenses related to studies designated in the Sanofi Agreement as RevMed Studies, for which we will bear all costs and expenses, and for the planned RMC-4630-03 study, for which we have agreed that Sanofi will reimburse us for 50% of the costs and expenses. Unreimbursed costs borne by us for any RevMed Studies and for our 50% share of the RMC-4630-03 collaboration study are subject to future reimbursement by Sanofi through a buy-in payment pursuant to the terms of the Sanofi Agreement if they use data from a RevMed Study or the RMC-4630-03 study in support of a marketing approval application. There currently are no active RevMed Studies.

We are responsible for the manufacture of SHP2 inhibitors for Phase 1 and non-registrational Phase 2 clinical trials pursuant to a development plan that is currently approved through 2022, while Sanofi is responsible for manufacturing SHP2 inhibitors for all other clinical trials and commercial supply. Sanofi has the sole right and responsibility to perform all regulatory activities under the Sanofi Agreement, except with respect to certain trials conducted by us or otherwise conducted under our IND, including our current clinical trials evaluating RMC-4630. Once we have completed all clinical trials for a product candidate that are assigned to us under a development plan, all regulatory approvals for such product candidate are automatically assigned to Sanofi.

We are also primarily responsible for performing preclinical research on SHP2 inhibitors, pursuant to a research plan that is currently approved through 2021. The parties currently do not anticipate additional collaboration preclinical research under the research plan in 2022. Sanofi is responsible to reimburse us for all internal and external costs and expenses incurred to perform activities under approved research plans, with the exception of internal and external research costs and expenses under the approved research plans for 2019 and 2020, for which Sanofi was obligated to reimburse us for 80% of such costs. We were responsible for 20% of all internal and external research costs incurred under the research plans for 2019 and 2020. Sanofi is responsible to reimburse us for all internal and external costs and expenses incurred under the research plan for 2021.

Unless otherwise delegated to us by the joint commercialization committee, Sanofi also has the sole right and responsibility for all aspects of the commercialization of SHP2 inhibitors in the world for any and all uses, at its expense, subject to our right to elect to co-promote SHP2 inhibitors in the United States. Sanofi is obligated to use commercially reasonable efforts to seek marketing approval for at least one SHP2 inhibitor product candidate in certain major market countries. Sanofi agrees to provide us, and we agree to provide Sanofi, with research, development and commercialization updates through the joint committees.

During the term of the Sanofi Agreement, we may not, alone or with any affiliate or third party, conduct certain research activities with respect to, or develop or commercialize, any product that contains a SHP2 inhibitor outside of the Sanofi Agreement.

Pursuant to the Sanofi Agreement, we received an upfront payment of $50 million from Sanofi in July 2018. Upon the achievement of specified development and regulatory milestones, Sanofi will be obligated to pay us up to $520 million in the aggregate, including up to $235 million upon the achievement of specified development milestones and up to $285 million upon achievement of certain marketing approval milestones. In the United States, we will share equally with Sanofi the profits and losses applicable to commercialization of SHP2 inhibitor products, pursuant to a profit/loss share agreement that the parties will negotiate based on key terms agreed in the Sanofi Agreement. On a product-by-product basis, Sanofi will also be required to pay us tiered royalties on annual net sales of each product outside the United States ranging from high single digit to mid-teen percentages. The royalty payments are subject to reduction under specified conditions set forth in the Sanofi Agreement. Subject to certain exceptions, the royalties are payable on a product-by-product and country-by-country basis until the latest of the expiration of all valid claims covering such product in such country contained in the patents licensed to Sanofi under the Sanofi Agreement and the expiration of regulatory exclusivity for such product in such country.

Sanofi has the sole and exclusive right to file, prosecute and maintain any patents licensed to it pursuant to the Sanofi Agreement, as well as to enforce infringement of or defend claims against such patents that relate to SHP2 inhibitor products.

Unless terminated earlier, the Sanofi Agreement will continue in effect until the later of the expiration of all of Sanofi’s milestone and royalty payment obligations and the expiration of the profit/loss share agreement. Upon expiration of the Sanofi Agreement, the licenses granted to Sanofi thereunder shall become fully paid-up, royalty-free, perpetual and irrevocable. Sanofi may terminate the Sanofi Agreement in its entirety or on a country-by-country or product-by-product basis for any reason or for significant safety concerns, upon prior notice to us within certain specified time periods. Sanofi may terminate the Sanofi Agreement in its entirety upon our change of control, with prior notice. Either party may terminate the Sanofi Agreement if an undisputed material breach by the other party is not cured within a defined period of time, or immediately upon notice for insolvency-related events of the other party. We may terminate the Sanofi Agreement after a certain number of years if Sanofi develops a competing program without commencing a registrational clinical trial for a SHP2 inhibitor product candidate, and subject to certain other conditions. We may also

78

terminate the Sanofi Agreement at any time, if Sanofi ceases certain critical activities for SHP2 inhibitor product candidates for more than a specified period of time, provided that such cessations of critical activity were not a result of certain specified factors, and subject to certain other conditions. Upon any termination of the Sanofi Agreement with respect to any product or country, all licenses to Sanofi with respect to such product or country shall automatically terminate and all rights generally revert back to us. If the Sanofi Agreement is terminated, in its entirety or with respect to a product, other than by us for Sanofi’s material breach or insolvency, we may be required to pay Sanofi royalties on worldwide net sales of reverted products up to mid-single digit percentages based on the development and regulatory status of such reverted products, in each case subject to reductions in accordance with the terms of the Sanofi Agreement.

Through December 31, 2021, we have received an aggregate of $154.8 million from Sanofi, including the upfront payment and research and development expense reimbursements.

Financial Operations Overview

Collaboration revenue

Collaboration revenue consists of revenue under the Sanofi Agreement for our SHP2 program. We entered into the Sanofi Agreement in June 2018. We received a $50.0 million upfront payment from Sanofi in July 2018, receive reimbursement for research and development services, and are entitled to future potential development and regulatory milestones.

For further information on our revenue recognition policies, see “Note 2. Summary of significant accounting policies” in the “Notes to Consolidated Financial Statements” contained in Part II, Item 8 of this Annual Report on Form 10-K.

Research and development expenses

We substantially rely on third parties to conduct our preclinical studies, clinical trials and manufacturing. We estimate research and development expenses based on estimates of services performed, and rely on third party contractors and vendors to provide us with timely and accurate estimates of expenses of services performed to assist us in these estimates. Research and development expenses consist primarily of costs incurred for the development of our product candidates and costs associated with identifying compounds through our discovery platform, which include:

•
expenses incurred under agreements with third-party contract organizations, investigative clinical trial sites that conduct research and development activities on our behalf, and consultants;

•
costs related to production of clinical and preclinical materials, including fees paid to contract manufacturers;

•
laboratory and vendor expenses related to the execution of discovery programs, preclinical and clinical trials;

•
employee-related expenses, which include salaries, benefits and stock-based compensation; and

•
facilities and other expenses, which include allocated expenses for rent and maintenance of facilities, depreciation and amortization expense, information technology and other supplies.

We expense all research and development costs in the periods in which they are incurred. Costs for certain development activities are recognized based on an evaluation of the progress to completion of specific tasks using information and data provided to us by our vendors, collaborators and third-party service providers. Nonrefundable advance payments for goods or services to be received in future periods for use in research and development activities are deferred and recorded as prepaid assets. The prepaid amounts are then expensed as the related goods are delivered or as services are performed.

Sanofi is responsible to reimburse us all internal and external costs and expenses to perform our activities under approved development plans, except for 50% of the RMC-4630-03 study and any future RevMed Study. Additionally, Sanofi is responsible to reimburse us for all internal and external costs and expenses incurred to perform activities under approved research plans for RMC-4630, with the exception of internal and external research costs and expenses under the approved research plans for 2019 and 2020, for which Sanofi was obligated to reimburse us for 80% of such costs. We were responsible for 20% of all internal and external research costs incurred under the research plans for 2019 and 2020. Sanofi was responsible to reimburse us for all internal and external costs and expenses incurred under the research plan for 2021. These reimbursements from Sanofi are recorded as collaboration revenue.

We expect our research and development expenses to increase for the foreseeable future as we continue to invest in discovering and developing product candidates and advancing product candidates into later stages of development, which may include conducting larger clinical trials. The process of conducting the necessary research and development and clinical trials to seek regulatory approval for product candidates is costly and time-consuming, and the successful development of our product candidates is highly uncertain. As

79

a result, we are unable to determine the duration and completion costs of our research and development projects or clinical trials or if and to what extent we will generate revenue from the commercialization and sale of any of our product candidates.

General and administrative expenses

General and administrative expenses consist primarily of personnel-related costs, consultants and professional services expenses, including legal, audit, accounting and human resources services, insurance, allocated facilities and information technology costs, and other general operating expenses not otherwise classified as research and development expenses. Personnel-related costs consist of salaries, benefits and stock-based compensation. Facilities costs consist of rent, utilities and maintenance of facilities. We expect our general and administrative expenses to increase for the foreseeable future due to anticipated increases in headcount and as a result of operating as a public company, including expenses related to compliance with the rules and regulations of the Securities and Exchange Commission, the Nasdaq Global Select Market, additional insurance expenses, investor relations activities and other administrative and professional services.

Interest income

Interest income primarily consists of interest earned on our cash equivalents and marketable securities.

Interest expense

Interest expense primarily consists of interest related to our finance lease and interest on other outstanding obligations.

Benefit from income taxes

Benefit from income taxes relates to net changes in the deferred tax liability associated with our Warp Drive acquisition resulting from changes in the effective state tax rate and changes in our valuation allowance.

Results of operations

Comparison of the years ended December 31, 2021 and 2020

Collaboration revenue

Collaboration revenue, consists of revenue under the Sanofi Agreement. In August 2021, we entered into a Letter Agreement with Sanofi to include RMC-4630-03 under the development plan for RMC-4630 ceased enrollment of new patients in RMC-4630-02. As a result of these development plan adjustments, we revised our estimate of the accounting transaction price and our percentage of

80

completion under the agreements with Sanofi, which resulted in a cumulative catch-up adjustment that reduced collaboration revenue by $8.5 million for the year ended December 31, 2021.

Collaboration revenue decreased by $13.6 million, or 32%, during the year ended December 31, 2021 compared to the same period in 2020. The decreases are primarily due to the cumulative catch-up adjustment and lower reimbursed manufacturing costs.

Research and development expenses

Research and development expenses increased by $54.7 million, or 41%, during the year ended December 31, 2021 compared to the same period in 2020. The increase in research and development expenses during the year ended December 31, 2021 was primarily due to a $34.5 million increase in third party costs for our preclinical research portfolio, primarily driven by higher chemistry contract research organization, material sourcing and manufacturing costs; a $9.2 million increase in salaries and other employee-related expenses due to increased headcount to support our research and development programs, a $7.0 million increase in stock-based compensation and a $5.4 million increase in facilities and other allocated expenses as a result of higher rent, utilities and information technology expenses associated with increased headcount.

General and administrative expenses

General and administrative expenses increased by $9.0 million, or 42%, during the year ended December 31, 2021 compared to the same period in 2020. The increase in general and administrative expenses during the year ended December 31, 2021 was primarily due to an increase of $4.8 million in stock-based compensation expense; an increase of $2.3 million in salaries and other employee-related expenses due to increased headcount; and an increase of $0.8 million in insurance.

Interest income

Interest income decreased by $1.3 million for the year ended December 31, 2021, compared to the same period in 2020 due to lower interest rates.

Interest expense

Interest expense was less than $0.1 million for both years ended December 31, 2021 and 2020.

Benefit from income taxes

Benefit from income taxes was zero for the year ended December 31, 2021 and $0.4 million for the year ended December 31, 2020 and relate to net changes in the valuation allowance resulting from the Warp Drive acquisition.

On March 27, 2020, the United States enacted the Coronavirus Aid, Relief, and Economic Security Act, or the CARES Act, as a result of the Coronavirus pandemic, which contains among other things, numerous income tax provisions. Some of these tax provisions are expected to be effective retroactively for years ending before the date of enactment. We have evaluated the current legislation and at this time, do not anticipate the CARES Act to have a material impact on its financial statements.

Comparison of the years ended December 31, 2020 and 2019

Collaboration revenue

Collaboration revenue decreased by $7.1 million, or 14%, during the year ended December 31, 2020 compared to the same period in 2019. The decrease in collaboration revenue during the year ended December 31, 2020 was primarily due to lower research and development costs incurred by us for our SHP2 program under the Sanofi Agreement resulting from lower manufacturing costs, which were partially offset by higher clinical trial costs. During the year ended December 31, 2019, we incurred upfront manufacturing costs related to the supply of RMC-4630 for our clinical trials.

Research and development expenses

Research and development expenses increased by $40.5 million, or 44%, during the year ended December 31, 2020 compared to the same period in 2019. The increase in research and development expenses during the year ended December 31, 2020 was primarily due to a $36.1 million increase in third party costs for our preclinical research portfolio, primarily driven by higher chemistry contract research organization, material sourcing and manufacturing costs for our pre-clinical activities; a $5.6 million increase in salaries and other employee-related expenses due to increased headcount to support our research and development programs; a $3.1 million increase in stock-based compensation; a $1.3 million increase in facilities and other allocated expenses as a result of higher rent, utilities and information technology expenses associated with increased headcount; offset by a decrease of $5.9 million in third-party expenses for our SHP2 program resulting from lower manufacturing costs as we incurred upfront manufacturing costs related to the supply of RMC-4630 for our clinical trials.

General and administrative expenses

General and administrative expenses increased by $9.0 million, or 73%, during the year ended December 31, 2020 compared to the same period in 2019. The increase was primarily due to an increase of $2.8 million in insurance costs as a result of becoming a public company; an increase of $2.7 million in stock-based compensation expense; an increase of $2.0 million in salaries and other employee-related expenses due to increased headcount; and an increase of $0.8 million in legal and accounting expenses.

Interest income

Interest income increased by less than $0.1 million the year ended December 31, 2020 compared to the same period in 2019. The increase was due to interest income earned from higher average investment balances resulting from the net proceeds from our Series C preferred stock financing in 2019, initial public offering in February 2020 and follow-on public offering in July 2020 offset by lower interest rates.

82

Interest expense

Interest expense was $0.1 million for both years ended December 31, 2020 and 2019.

Benefit from income taxes

Benefit from income taxes was $0.4 million for the year ended December 31, 2020 and relates to a reduction in the effective state tax rate and the resulting impact on the deferred tax liabilities from the Warp Drive acquisition. Benefit from income taxes was $4.4 million the year ended December 31, 2019 and relates to net changes in the valuation allowance resulting from the Warp Drive acquisition.

Liquidity and capital resources

In February 2020, we closed our IPO and issued 16,100,000 shares of our common stock at a price to the public of $17.00 per share for net proceeds of approximately $250.7 million, after deducting underwriting discounts and commissions of $19.2 million and expenses of $3.8 million.

In July 2020, we issued 6,900,000 shares of our common stock in an underwritten public offering at a price of $26.00 per share for net proceeds of $167.8 million, after deducting underwriting discounts and commissions of $10.8 million and offering expenses of $0.8 million.

In February 2021, we issued 6,666,666 shares of our common stock in an underwritten public offering at a price of $45.00 per share for net proceeds of $281.3 million, after deducting underwriting discounts and commissions of $18.0 million and offering expenses of $0.7 million.

In November 2021, we entered into a sales agreement with Cowen and Company, LLC (Cowen) to sell shares of our common stock, from time to time, with aggregate gross proceeds of up to $250 million, through an at-the-market equity offering program (ATM) under which Cowen agreed to act as our sales agent. From November 2021 to December 31, 2021, we sold an aggregate of 339,302 shares of common stock under the ATM resulting in gross proceeds to us of $10.4 million. After deducting commissions and expenses of $0.3 million, net proceeds to us were $10.1 million.

Our operations have been financed primarily by our public offerings of common stock, net proceeds of $230.6 million from the issuance of our preferred stock and $154.8 million received under the Sanofi Agreement for upfront payments and for research and development cost reimbursement.

As of December 31, 2021, we had $577.1 million in cash, cash equivalents and marketable securities.

As of December 31, 2021, we had an accumulated deficit of $452.6 million. Our primary use of cash is to fund operating expenses, which consist primarily of research and development expenditures related to our product candidates and our pre-clinical research portfolio, and to a lesser extent, general and administrative expenditures. We expect our expenses to continue to increase in connection with our ongoing activities, particularly as we continue to advance our product candidates and pre-clinical research portfolio.

We believe that our existing cash, cash equivalents and marketable securities will enable us to fund our planned operations for at least 12 months following the date of this report.

The timing and amount of our future funding requirements depends on many factors, including:

•
the scope, progress, results and costs of researching and developing our product candidates and programs, and of conducting preclinical studies and clinical trials;

•
the timing of, and the costs involved in, obtaining marketing approvals for product candidates we develop if clinical trials are successful;

•
the success of our collaboration with Sanofi, including the continued reimbursement by Sanofi of substantially all of our research costs and all of our development costs for our SHP2 program under the Sanofi Agreement (other than for the RMC-4630-03 study or any RevMed Studies);

•
whether we achieve certain clinical and regulatory milestones under the Sanofi Agreement, each of which would trigger additional payments to us;

83

•
the cost of commercialization activities for RMC-4630, to the extent not borne by Sanofi, and any other future product candidates we develop, whether alone or in collaboration, including marketing, sales and distribution costs if RMC-4630 or any other product candidate we develop is approved for sale;

•
the cost of manufacturing our current and future product candidates for clinical trials in preparation for marketing approval and in preparation for commercialization;

•
our ability to establish and maintain strategic licenses or other arrangements and the financial terms of such agreements;

•
the costs involved in preparing, filing, prosecuting, maintaining, expanding, defending and enforcing patent claims, including litigation costs and the outcome of such litigation;

•
the timing, receipt and amount of sales of, profit share or royalties on, our future products, if any;

•
the emergence of competing cancer therapies or other adverse market developments; and

•
any plans to acquire or in-license other programs or technologies.

We expect to need to obtain substantial additional funding in the future for our research and development activities and continuing operations. Sanofi reimburses us for almost all of our research and development expenses associated with our SHP2 program, however Sanofi has the right to terminate the Sanofi Agreement for any reason, upon prior notice to us within certain specified time periods and upon any such termination by Sanofi with respect to any product or country, all licenses to Sanofi with respect to such product or country shall automatically terminate and all rights generally revert back to us. If we need to raise additional capital to fund our operations, funding may not be available to us on acceptable terms, or at all. If we are unable to obtain adequate financing when needed, we may have to delay, reduce the scope of or suspend one or more of our clinical trials, research and development programs or commercialization efforts. We may seek to raise any necessary additional capital through a combination of public or private equity offerings, debt financings and collaborations or licensing arrangements. If we do raise additional capital through public or private equity offerings, the ownership interest of our existing stockholders will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect our stockholders’ rights. If we raise additional capital through debt financing, we may be subject to covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends, and if the debt is convertible into our common stock, the ownership interest of our stockholders may be diluted. If we are unable to raise capital, we may need to delay, reduce or terminate planned activities to reduce costs. Doing so will likely harm our ability to execute our business plans.

Cash flows

The following table summarizes our consolidated cash flows for the periods indicated:

Cash used in operating activities

During the year ended December 31, 2021, cash used in operating activities of $147.2 million was attributable to a net loss of $187.1 million partially offset by a net change of $31.2 million in non-cash charges and by net change of $8.7 million in our operating assets and liabilities. The non-cash charges primarily consisted of stock-based compensation expense of $20.7 million, depreciation and amortization of $4.2 million, and amortization of operating lease right-of-use asset of $3.2 million. The change in operating assets and liabilities was primarily due to $11.0 million increase in accrued expenses and accounts payable partially offset by $1.7 million decrease in deferred revenue associated with the Sanofi Agreement and $1.5 million decrease in operating lease liability.

During the year ended December 31, 2020, cash used in operating activities of $100.1 million was attributable to a net loss of $108.2 million and a net change of $8.3 million in our operating assets and liabilities, partially offset by a net change of $16.4 million in non-cash charges. The non-cash charges primarily consisted of stock-based compensation expense of $8.9 million, depreciation and amortization of $2.6 million, and amortization of operating lease right-of-use asset of $2.9 million. The change in operating assets and liabilities was primarily due to a $11.3 million decrease in deferred revenue associated with the Sanofi Agreement partially offset by a $4.9 million increase in accrued expenses and other current assets.

84

During the year ended December 31, 2019, cash used in operating activities of $49.6 million was attributable to a net loss of $47.7 million and a net change of $8.8 million in our operating assets and liabilities, partially offset by a net change of $6.9 million in non-cash charges. The non-cash charges consisted of depreciation and amortization of $2.9 million, stock-based compensation expense of $3.2 million, a loss on disposal of held for sale assets of $0.6 million and a loss on disposal of property and equipment of $0.2 million. The change in operating assets and liabilities was primarily due to a $13.4 million decrease in deferred revenue associated with the Sanofi Agreement, a $4.4 million decrease in deferred tax liability related to the net change in valuation allowance resulting from the Warp Drive acquisition, a $1.4 million increase in receivable from a related party resulting from the Sanofi Agreement and a $0.5 million increase in prepaid expenses and other current assets primarily resulting from the timing of prepayments made for research and development activities, partially offset by a $11.3 million increase in accounts payable and accrued liabilities resulting from increases in spend for research and development activities.

Cash used in investing activities

During the year ended December 31, 2021, cash used in investing activities of $142.1 million, was primarily comprised of purchases of marketable securities of $671.3 million and purchases of property and equipment of $6.5 million, offset by cash provided by maturities of marketable securities of $526.8 million and sale of marketable securities of $9.0 million.

During the year ended December 31, 2020, cash used in investing activities of $234.2 million, was primarily comprised of purchases of marketable securities of $544.1 million and purchases of property and equipment of $2.9 million, partially offset by cash provided by maturities of marketable securities of $309.8 million and sale of marketable securities of $3.0 million.

Cash provided by financing activities

During the year ended December 31, 2021, cash provided by financing activities of $294.2 million was comprised of $281.1 million in net proceeds from the issuance of common stock related to our public offering in February 2021, $10.1 million in net proceeds from the issuance of common stock under our ATM facility, $1.9 million in proceeds from the issuance of common stock under the employee stock purchase plan and $ 1.5 million in proceeds from the issuance of common stock upon the exercise of stock options.

During the year ended December 31, 2020, cash provided by financing activities of $422.8 million was comprised of $420.1 million in net proceeds from the issuance of common stock related to our IPO in February 2020 and our public offering in July 2020, $1.9 million in proceeds from the issuance of common stock upon the exercise of stock options and $0.8 million in proceeds from the issuance of common stock under the employee stock purchase plan.

During the year ended December 31, 2019, cash provided by financing activities of $98.7 million was comprised primarily of $100.0 million in net cash proceeds received from the issuance of our Series C redeemable convertible preferred stock and $0.3 million in proceeds from the issuance of common stock upon the exercise of stock options; partially offset by $1.6 million in payments of deferred offering costs related to the IPO which closed in February 2020.

Contractual obligations and commitments

We have contractual obligations related to office and laboratory space leases in Redwood City, California and Cambridge, Massachusetts, described in “Note 7. Commitments and contingencies” in the “Notes to Consolidated Financial Statements” contained in Part II, Item 8 of this Annual Report on Form 10-K.

We enter into agreements in the normal course of business with contract research organizations for clinical trials, contract manufacturing organizations to provide clinical trial materials and with vendors for preclinical studies and other services and products for operating purposes which are generally cancelable at any time by us upon 30 to 90 days prior written notice.

Off-balance sheet arrangements

We have not entered into any off-balance sheet arrangements, as defined in Item 303 of Regulation S-K.

85

Indemnification agreements

We enter into standard indemnification arrangements in the ordinary course of business. Pursuant to these arrangements, we indemnify, hold harmless and agree to reimburse the indemnified parties for losses suffered or incurred by the indemnified party, in connection with any trade secret, copyright, patent or other intellectual property infringement claim by any third party with respect to its technology. The term of these indemnification agreements is generally perpetual any time after the execution of the agreement. The maximum potential amount of future payments we could be required to make under these arrangements is not determinable. We have never incurred costs to defend lawsuits or settle claims related to these indemnification agreements. As a result, we believe the fair value of these agreements is minimal.

Critical accounting policies, significant judgments and use of estimate

Our management’s discussion and analysis of our financial condition and results of operations is based on our consolidated financial statements, which have been prepared in accordance with United States generally accepted accounting principles, or U.S. GAAP. The preparation of these consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements, as well as the reported expenses incurred during the reporting periods. Our estimates are based on our historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. We believe that the accounting policies discussed below are critical to understanding our historical and future performance, as these policies relate to the more significant areas involving management’s judgments and estimates.

Revenue recognition

We recognize revenue is accordance with Accounting Standards Codification Topic 606, Revenue from Contracts with Customers (ASC 606). Under ASC 606, an entity recognizes revenue when its customer obtains control of promised goods or services, in an amount that reflects the consideration which such entity expects to receive in exchange for those goods or services. In determining the appropriate amount of revenue to be recognized as we fulfill our obligations under arrangements, we perform the following steps: (i) identify the contract(s) with a customer, (ii) identify the performance obligations in the contract, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations in the contract, and (v) recognize revenue when (or as) the entity satisfies the performance obligation. At contract inception, once the contract is determined to be within the scope of ASC 606, we assess the goods or services promised within each contract and determine those that are performance obligations and assess whether each promised good or service is distinct. We then recognize as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied.

We enter into collaboration agreements under which we may obtain upfront license fees, research and development funding, and development, regulatory and commercial milestone payments and royalty payments. Our performance obligations under these arrangements may include licenses of intellectual property, sales and distribution rights, research and development services, delivery of manufactured product and/or participation on joint steering committees.

Licenses of intellectual property: If the license to our intellectual property is determined to be distinct from the other performance obligations identified in the arrangement, we recognize revenue from upfront license fees allocated to the license when the license is transferred to the customer and the customer is able to use and benefit from the license. For licenses that are bundled with other promises, we utilize judgment to assess the nature of the combined performance obligation to determine whether the combined performance obligation is satisfied over time or at a point in time and, if over time, the appropriate method of measuring proportional performance for purposes of recognizing revenue from non-refundable, upfront fees. We evaluate the measure of proportional performance each reporting period and, if necessary, adjust the measure of performance and related revenue recognition.

Research, development and regulatory milestone payments: At the inception of each arrangement that includes research, development, or regulatory milestone payments, we evaluate whether the milestones are considered probable of being reached and estimate the amount to be included in the transaction price. We use the most likely amount method for research, development and regulatory milestone payments. Under the most likely amount method, an entity considers the single most likely amount in a range of possible consideration amounts. If it is probable that a significant revenue reversal would not occur, the associated milestone value is included in the transaction price.

Sales-based milestones and royalties: For arrangements that include sales-based milestone or royalty payments based on the level of sales, and in which the license is deemed to be the predominant item to which the sales-based milestone or royalties relate to, we recognize revenue in the period in which the sales-based milestone is achieved and in the period in which the sales associated with

86

the royalty occur. To date, we have not recognized any sales-based milestone or royalty revenue resulting from our collaboration arrangements.

The transaction price for each collaboration agreement is determined based on the amount of consideration we expect to be entitled for satisfying all performance obligations within the agreement. Significant judgment may be required in determining the amount of variable consideration to be included in the transaction price. We use the most likely amount method to determine variable consideration and will re-evaluate the transaction price in each reporting period and as uncertain events are resolved or other changes in circumstances occur.

Revenue is recognized based on actual costs incurred as a percentage of total estimated costs to be incurred over the performance obligation as we fulfill our performance obligations. A cost-based input method of revenue recognition requires management to make estimates of costs to complete our performance obligations. In making such estimates, significant judgment is required to evaluate assumptions related to cost estimates. The cumulative effect of revisions to estimated costs to fulfill our performance obligations will be recorded in the period in which changes are identified and amounts can be reasonably estimated.

Accrued research and development expenses

We record accrued expenses for estimated preclinical studies and clinical trial expenses. Estimates are based on the services performed pursuant to contracts with research institutions and contract research organizations and clinical manufacturing organizations that conduct and manage preclinical studies and clinical trials on our behalf based on actual time and expenses incurred by them. Further, we accrue expenses related to clinical trials based on the level of patient enrollment and activity according to the related agreement. We monitor patient enrollment levels and related activity to the extent reasonably possible and make judgments and estimates in determining the accrued balance in each reporting period. If we underestimate or overestimate the level of services performed or the costs of these services, our actual expenses could differ from our estimates. To date, we have not experienced significant changes in our estimates of preclinical studies and clinical trial accruals.

Stock-based compensation

We maintain an equity incentive plan as a long-term incentive for employees, consultants and members of our board of directors. The plan allows for the issuance of non-statutory options, or NSOs, incentive stock options, or ISOs, restricted stock unit awards, or RSUs to employees and NSOs and RSUs to nonemployees.

Stock-based compensation is measured using estimated grant date fair value and recognized as compensation expense over the service period in which the awards are expected to vest. The grant date fair value of an RSU award is based on our stock price on the date of grant. For options, we estimate the grant date fair value, and the resulting stock-based compensation, using the Black-Scholes option-pricing model, and we use the straight-line method for expense attribution. The Black-Scholes model requires us to make assumptions and judgments about the variables used in the calculations, including the expected term (weighted-average period of time that the options granted are expected to be outstanding), the expected volatility of our common stock, the related risk-free interest rate and the expected dividend. We have elected to recognize forfeitures of stock-based awards as they occur.

The Black-Scholes option-pricing model requires the use of highly subjective assumptions to determine the fair value of stock-based awards. These assumptions include:

•
Expected Term— The expected term is calculated using the simplified method, which is available where there is insufficient historical data about exercise patterns and post-vesting employment termination behavior. The simplified method is based on the vesting period and the contractual term for each grant, or for each vesting-tranche for awards with graded vesting. The mid-point between the vesting date and the maximum contractual expiration date is used as the expected term under this method.

•
Expected Volatility— Given that we do not have sufficient trading history for our common stock, the expected volatility was estimated based on the average volatility of the Company and comparable publicly traded biotechnology companies over a period equal to the expected term of the stock option grants. The comparable companies were chosen based on their similar size, stage in the life cycle or area of specialty.

•
Risk-Free Interest Rate—The risk-free interest rate is based on the U.S. Treasury zero coupon issues in effect at the time of grant for periods corresponding with the expected term of the option.

•
Expected Dividend—We have never paid dividends on our common stock and have no plans to pay dividends on our common stock. Therefore, we used an expected dividend yield of zero.
